This is the BEST little know app EVER that will save you time at the airport, and that’s coming from an airline employee of over 5 years. It was amazing the estimated wait time was almost 2 hours or more for the regular person who doesn’t have a Global Entry Number. That said when your traveling through an entry point city that the worlds largest airline uses as one of their international hubs and just want to get through the Customs and Border Protection line at the airport when entering These United States, you have go to download this app !!! You can choose to have it save your passport information, or you can have it rest each time your forms for entry expire, all you have to do is take a clear picture of yourself, and a picture of your passport and enter your flight information and then fill out the quick standard entry question, and then the app auto fills out the correct entry forms for you and your entire family who might be traveling with you. Then you pick up your checked baggage (if you have any), and lastly start looking for the signage for the line for electronic entry. I will say this global entry was way way longer then this apps line and that is supposed to be the timesavers line for frequent international travelers, and this app allowed us to even cut in front of them without having to pay for anything!!!
If you've been using the Mobile Passport app and, like me, have seen it saying lately that it will no longer relay your information to U.S. Customs & Border Patrol (CBP), it's time to cancel your subscription to Mobile Passport, delete that app, and download this one. CBP MPC is the official and up-to-date replacement for the Mobile Passport app. And I'm not positive yet, but it's looking to me like this one doesn't even require a subscription to do what Mobile Passport did (and more, I think). And if you *haven't* been using the Mobile Passport app but are looking for an electronic repository for your passport and a paperless means of filling out the forms necessary for entry into the U.S. and/or Canada, this is the app you're looking for too. It's the official one, put out by the Department of Homeland Security and all that jazz, and not some third-party thing that adds an unnecessary link to the chain of communication. Enjoy. 🙂👍🏻
It may be coincidence, but with the retirement of the Airside app, it seems that immigration control at fewer and fewer airports are processing the Mobile Passport Control receipt. Instead of getting the expedited service we users formerly received, we are being dumped into the same long lines all other travelers (many very unfamiliar with the basics) are using. The result is a very substandard experience and excessive processing time — hardly what we had grown to expect from the program when originally launched. At the very least, those airports that have removed the receipt scanners and don’t provide dedicated servicing for Mobile Passport should be removed from the “port of entry” list. Leaving them in there sets a false expectation that we will be able to use the app and get through quickly. Today I nearly missed a connection at O’Hare because the airport refuses to use the app (even though they show up on the list). It seems to be a locally-driven decision. Even better would be to mandate the use of the system at all major US gateway airports. It used to provide a useful alternative for those of us who travel frequently, but don’t live near a major airport where we can schedule a Global Entry interview (and go through that ponderous bureaucratic process). US CBP needs to make up their mind what their mobile strategy is… and then follow through with a consistent and convenient execution of that strategy!
Contrary to many 1* reviews the App is very easy to use. The only design defect is that you have to start at the “Begin Your Entry Process” screen, select “Airplane” or “Cruise Ship” - which does not matter at that point - and only than start adding travelers. Once that step is complete, you cancel the entry form, and the data will remains recorded in the App. Once you are about to arrive you go to that same “Begin Your Entry Process” screen, and on the next page select from those travelers profiles that you have already created. The actual experience at the airport may vary. In EWR in September there were clearly marked signs for MPC, however that was the same line as for the crew, which was actually a bit longer than the regular line. (Which was uncharacteristically short at the time.) In PHL in December the MPC line was “hidden in plain sight”: there was a huge sign, but it was different in style from all the other signs directing the traffic, and our family has missed it on the first pass. However going through that line saved us at least half an hour or more. At any event, with MPC there’s always an option to just use regular line if it looks shorter.
Great when they open it up- Useless when they don’t
Arrived in Miami this morning around 0450. Completed the Mobile App as did many many others ( you advertise to use it, so we do). All of us had connecting flights. Hurry to the US citizen line, and the mobile app lane is CLOSED. Asked one of the agents for the Mobile App line-stated it was closed. Over 100 people in line most with connecting flights. Only 3 agents working to process passengers. Multiple times the agent at the head of the line was told about the connecting flights. Let 1 guy go, but no others. Suddenly 9 people came from somewhere else and were able to jump the line! THE PROCESS WAS SO SLOW!! Many of us at the end missed flights. I have used it before and it was GREAT. Not today
I learned about this app on Instagram. When we arrived back home from our Europe vacation I figured let’s give it a try. I inputted all our passports 5 of us. Took pictures of our faces as soon as we landed. Walked to immigration. Asked an officer where do I go with mobile passport and walked us to the global entry line. Passed immigration so fast that I wasn’t sure what happened. I looked back and saw the big line that we skipped. When we arrived to baggage claim we were the only ones there and got our luggage and left. The rest of the passengers were still waiting on the immigration line to pass. This was so easy and amazing especially after a long day of flying and anxiously wanting to get back home.
The OCR optical character recognition is great. it’s not perfect. you do have to go through each field and check. The camera during pictures taken shows a different view of what’s displayed after you try to submit what was take. the top of the heads are cropped no matter what angle or how far back the person is. i’m taking the picture and over and over and over again and I can’t seem to get the top of the head and during the validation part. The staff at the airport are not clearly stating that you can go into a different line by using this app. the sign about this app doesn’t distinguish itself by name so basically uses the word mobile ambiguously. So basically we stood in this long line for nothing, and filled out the forms on this app for nothing as well.
Gets the Job Done, but overall CBP scanning workflow needs to improve
Mobile Passport is (in my opinion) still relatively unknown, so there is clearly an advantage for those who use it. I was able to skip the general CBP line and go straight to an agent's counter via the Mobile Passport line. The form itself is self-explanatory and easy to fill out. After submission you receive a barcode on the app to scan at the counter. This is where I suggest some improved functionality on the app. I was not able to tell whether my barcode had scanned so I held my phone against the scanner for a bit. (I did not see the scanner "blink" or hear any "blink" noise to suggest that it scanned.) The agent at my counter subsequently got in his feelings and became rude to me because I had accidentally scanned my barcode more than once. If it is that important for the barcode to be only scanned once, I would suggest including a confirmation message app-side when the barcode has been scanned OR at least a disclaimer message when presenting the barcode. This is pretty common for high-profile retail apps nowadays. As a proud American citizen returning home from abroad I expect a smoother experience especially when using a mobile app designed to be seamless.
The app was fantastic! I read everything, took my time to put the information in , was thrilled to be able to use it the first time at Atlanta airport customs— breezed through the QR view line, was almost at the window when: THE CUSTOMS AGENT IN STALL # 37, on Nov 8, 2023, at 6pm, stepped out of his stall and did NOT COME BACK!! We waited and waited; seeing others from our flight go through the regular line!!! Finally a security person opened the 38 lane and “I don’t have a scanner”, so all of the preparations was for nothing!! Well, guess I will have to go abroad again so I can use the app once again— maybe the next time I will be overjoyed!!
Location requirement breaks the app in a lot of places
I’ve been in the terminal at the decision point between mobile passport line and normal line, in the app still tells me I’m too far away. What’s even more of an issue is that deep in the bowels of these government buildings, often the mobile reception is not great so your location data isn’t so precise. This requirement needs to be loosened up so that we can submit while on the taxiway. And why does it let me use the app in places when there isn’t support for it? LAX hasn’t supported this in years but you can certainly fill out your form, take pictures and then submit it. When everything works, it does save a little time over when the electronic kiosks are working. But i’ve water more time on when it doesn’t work than i’ve saved over 25-30 trips (I’m including the previous privatized version of the app with which I had more success).
First off, read the description about the app carefully. You can’t submit your info until you arrive. You will still need to present your US passport to the CBP agent. The system works is you pay attention to details. Flew back to Dulles Airport from the Caribbean in June 2024 using the MPC app. Had initial issues with connecting to CBP server but it worked before we board the shuttle to the terminal. Hundreds of people in regular line. Less than 10 people in the MPC line! Out of the airport and in a taxi in less 45 minutes after landing.
I got this app and was excited to see if it helps with the long lines. We were on a plane with 383 other people, we were the 5th family in line at the MPC line…… this line shares with the flight crew AND Global Entry….. as more flights were landing, we were left waiting as other priorities came first. The regular line went through our entire plane and some of the 2nd flight before our turn. The employees helping with the line said it’s our fault for choosing the mobile option. The flight crew also said the regular line is always faster in their opinion. The app is fine and when the airport employees catch up…. It might work better. I won’t use the app again as we waited way to long.
The last two times I have tried to use this it was pointless. The first one, in Charlotte, the line using mobile passport was longer than the regular line. That was likely because the global entry people automatically got in front of single mobile passport line and the regular lines kept going through. So every time a new plane landed, a dozen or more people with global entry and airline employees went in front of the mobile passport line even though there were hundreds of MPC people in it. And the regular lines kept going with nobody getting in front of it Then, tonight, in Dallas, MPC was not an option. They only had 2 CBP lines total and no MPC lines available. What’s the point of having an app that we spend time putting our information in and taking photographs of us and then not having anybody using it at the airport?
App assigns lane numbers that don’t even matter, as well as horrible assistance
After filling out the MPC, the app gives you a lane number to go through. After waiting in the front of the line for the MPC, we assumed that we had to walk to given lane since no one was really directing any of the lines. As we began walking, one of the workers told us to get back in line. When we asked if the lane numbers meant anything, she cut us off and sent us to a lane completely different from the one assigned. There was a lot of frustration with the app itself having useless information, as well as the horrible service from the workers we were trying to cooperate with. Excluding the lane numbers would have probably saved us from the stress of figuring out what to do for customs.
What is the use of this app at New York JFK airport, International terminal 7? It was completely useless and there were no short lines, the agent asked us everything that we already answered in the app, and he didn’t even want to see anything in the app. So I asked him what the purpose of the app wasn’t and he said they don’t use it. They were also severely understaffed with only total six agents, handling three international flights, with only three assigned to US citizens and three assigned to everybody else. We are US citizens and what they do at JFK is a total joke.
As we all know, traveling these days is a grind. The last thing you need when getting home is to wait in a long line at Customs. So don't! Get this official app instead and skip the lines. Fill out the easy form before you land, submit it when you land, then in Customs, watch for signs for the MOBILE PASSPORT lane. Just a dozen in line for that, VS hundreds in the regular line yesterday at Logan Airport, Boston. Pssst!! But don't tell anyone! We don't want this to get too popular and ruin it for those in the know :)
This is the first time we use the “mobile passport clearance” application to clear customs during our trip from Europe. It was easy to use and allow us to expedite entry into the United States. Only one person per family needs to install the MPC application in the celular to be able to use this process. The App allows you to scan the barcode of the passport to add all those who are traveling together, then answering a few questions and ready! If you have not tried it, please use it.
I used this last night at Logan Airport (Boston). I remembered I downloaded it the day before my return from London. I completed the form quickly and just left the page open on the submit form page. Upon landing I took the picture as required and hit submit form button. The lines at passport control were some of the longest I have seen at Logan. The MPC line, one couple in front of me. I was done in 5 minutes! Love it! So glad I decided to use it. I think I heard about it on a FB reel.
I’ve only used the MPC app when entering the country at San Francisco Int’l Airport. But it’s been a breeze every time. Never more than 1-2 groups ahead of us in the MPC line and seems faster than the CLEAR lane. So long as you have internet service once you land (either thru your own phone data service or the airport’s WiFi), it will be quick and easy. If you have a short international flight back to the U.S., you can submit your info. before you even get on your flight. Your submission is valid for 4 hours. This app is a hidden gem. It’s free to use and I’m surprised more people aren’t using it. TSA pre-check isn’t as fast as it was before … and you have to pay for that. Maybe as people catch onto MPC, the time savings may not be worth it. Or maybe there will eventually be a fee to use MPC. But for now, it’s free gold.
I saw a sign advertised in this app as I arrived at JFK. I install the app photograph, my passport photograph myself, and filled out all the information, answering all the questions. Then I went and stood in line a passport control in the line that said mobile app. The line barely moved, and people who came in the same time as me in the general line, moved much faster and were out of the airport before I even got to the front of the mobile app line. When I got to the front the officer asked me all the same questions, took my picture, and when I asked him why I have to do that. If I use the mobile app, he said that he got snow information from the mobile app and he doesn’t know what it’s for.. So this app is utterly useless.
The old mobile passport was awesome to save time coming in through customs at DIA, and I got this new version for the same easy pass to the front of the line - but apparently nowadays they’ve decided the app takes longer and DIA has abandoned using it. Unless you have global entry they make you wait with everyone else. Then when you do get to the agent they say the app is a mess and they are faster to check you through manually. Huge bummer. Uninstalling. And after the mess at DIA I likely will keep my travels within the U.S.! We got into Cancun faster (on a Friday afternoon) than we got back into DIA on a Thursday evening. It is just too hard with kids to deal with that after traveling from another country.
I tried to enter my traveler information several times. Every time I would try to submit my information, the app would crash and close. I tried downloading the app twice to no avail. Additionally, the setup and framework of the app was unnecessarily complicated and overly print rich, making it easy to miss critical information and make mistakes while using the app. I do not recommend this app at all —it proved to be completely inefficient and unusable.
We used this app when flying from Los Cabos to LAX, Tom Brady International Terminal. Very easy to enter your information before your trip and then when you land just answer the questions and take the photo. When we arrived to the custom the regular line was very long and the mobile passport line only had one family ahead of us. We went through customs in under 10 minutes. I highly recommend this app to anyone who doesn’t travel internationally often to do Global Entry.
Can back from travel with my family and walked up to a line at immigration that would take us over an hour to get through. I noticed someone walking into the global entry line and asked her what the difference was. She lead me to this app and in less than 5 mins my family and I were all set and walking into the global entry line! Thank you for making the traveling process so much easier!
We were leaving Calgary, Canada flying to DFW. Our port of entry back into the US would be DFW, in our estimation. When we arrived at the Calgary airport the app said it we were too far from our port of entry for it to accept or submit our declaration form. As we were standing outside the Customs line, a helpful lady said we needed to list Calgary as our POE. So, we deleted DFW and added Calgary instead. The app said we were still too far from our POE. The lady then took my phone and app to a Customs officer and he couldn’t ascertain what went wrong either. We never could get this durn app to work after multiple deletes and retries. We waited and went thru the general Customs line…..that this app was supposed to circumvent.
Finding out about this app while its still somehow unknown is great. Used it for the first time this week while returning to the US through LAX and I was the only person in line. I was through customs in less than 30 seconds, faster than Global Entry, and all for free. Set up the app and your profile before you travel, then do your submission while you wait to deboard your flight. I’m sure eventually the line will get long as people discover the app but for now its fantastic. If your passport scans on egates then this app will work without issue.
I was a big supporter of Mobile Passport and was surprised when I found out that CBP MPC was now the official app to be used at U.S. Customs & Boarder Patrol. I downloaded the new app and entered the necessary information as required. Upon landing at Newark International Airport, I was disappointed to find out there was no longer a separate entry for CBP MPC customers that previously was available for Mobile Passport. So I am not sure what the benefits are to the new app and what services it provides? After waiting in line and showing the agent the information on the app, he actually got mad at me and said the app is “useless”. So the question I have is what advantages does this app have for international travelers? From practical experience, none!
The movement of the passport and the image on the screen on an iPad do not seem to be coordinated. I found it very difficult to place our passport image pages into the screen. Fortunately with multiple attempts the program seemed to acquire all the information that it needed. The information was correct. I could not verify the images and may have my wife’s Face ID for my information on our joint Mobile Passport Control record.
Great App and extremely convenient to use and save time for the immigration clearance The baggage information is quite a unique feature and extremely helpful If additional features like the airport map layout and the connecting flight information can be added then it will be a fantastic option for users who come on an international flight and have to connect on a domestic flight Overall ⭐️⭐️⭐️⭐️⭐️🙏🏼
This app was promoted in Deltas app when I was checking in for my return flight from Paris today. I was excited to see how well it would work. I filled out all the info for my wife and I. We were ready when we arrived at immigration. I asked what line to go to for the app. I was told that no one in ATL F terminal was open to accept it. I was very frustrated to hear since Delta suggested I download and use the app for my arrival. I was stuck in the regular line. As for the App itself. I found it easy to use. Sometime soon I hope to try it.
I was more than willing to use the app . It is definitely a much needed option if a person has nothing to declare. However, I am a resident alien of US and when filling out the ?s and proceeding , there is no Option for returning Resident alien. The ground crew were very nice and the customs officer processed me in seconds. I might not be so lucky next time. It caused me a lot of tension because if I selected one of the two options , I would be lying about why I was coming back home. I didn’t want that on my INS record. Please add the option for citizens and legal residents to clear in fast pass.
The app is easy to use, but although MIA does have signage for it, the CBP here apparently does not (or does not always) utilize this app. All the CBP windows labeled as MPC were unmanned., and we were directed back into the regular line. When I reached the front and presented my MPC receipt to the CBP officer, they ignored it and instead processed me as a normal entry (passport, 6 questions, etc.) So, nice idea, and could help speed up lines, but MIA needs to improve organization to support this.
Landed in IAD yesterday 4/1/22 and they held us on the transport bus for 10 minutes because the immigration hall was full. I would guess around a 2-3 hour wait. We joined the mobile queue with one person in front of us and were through in less than 5 minutes. I assume as the app gains popularity that the line will get longer, but at the time of writing I can’t emphasize how much better of an experience this was.
In the past we used the Mobile Pass app but that has now been replaced with this one. It works basically the same. Scan your all of your family’s passports, take selfies, answer some questions and submit once you land. When you get to immigration, make sure you get in the mobile passport lane and you basically jump to the front. Not sure why more people don’t know about this app.
I just used the CBP passport app and it works well. Simple questions. I fuss. It needed one re-try on the picture of the passport. I guess it is the weird reflective surface. But then it worked. I also had to resubmit it once (but without re-entering any information, which is better than most apps). Second time the submission went through. No problem. Prep work: think of your four digit PIN the app will ask you to create.
Great app, but useless if the airport doesn’t open a lane for it. It all depends On The Airport! People, please identify the airport and whether the app worked/immigration had a dedicated line or not when you write the comment. Without this info and just complaining the app doesn’t work is not helpful to anyone! I have used it many times at Newark (EWR) and there’s basically no wait. But they don’t accept MPC anymore. The app is useless there now. Don’t blame the app, it’s the people who run the airport and won’t open the MPC lane that’s to blame! Lazy bums.
I recently flew in from Mexico and as I rounded the corner to customs after getting off the plane, the Global Entry line looked almost as long as the regular line. I walked passed EVERYONE to the booth at the end of the row and handed a gentleman my drivers license along with my phone with the app activated. He asked me a few questions regarding my trip and wished me a good day. It was almost as exciting as my trip. I just wish I could use it at the DMV line lol.
I was watching travel hacks on TikTok because i had just recently been traveling out of the country for the first time, and i came across a video about this app. I didn’t think it’d be legit, or as fast as they said it was. But WOW! The customs line was PACKED, but the Global Entry/MPC line took about SIX MINUTES. The app was also super easy to navigate and the entire process was super streamlined. All in all, simply the best travel app for returning to the US.
Love this app and always use it when and where it is available. It can be a real time saver, something nice and much appreciated when one is tired from long travel and just wants to get on with it and get home. It does need some minor tweaking from time to time, but it is totally deserving of my 5 star rating, which I don’t often give😊👍!
Once we got to the counter (MCO), the CBP agent said they didn’t have readers for it, and they hadn’t been using the app for about 12 years. Despite the TVs in the hall advertising the app, it appears that the “new” app hasn’t tricked down to the frontline staff. Not that it would have saved much time, as there were no self-service kiosks in the terminal, the real wait was being stuck behind 400 other people… Hopefully it will work out next time. It reads the passport really quickly and application was easy to complete.
It does not say that passengers with global entry should NOT use this app. I had to return to the kiosk to fill out the global entry form and got the notice that my last US entry was too recent. It was two months before, so I guess this app updated my data even before I passed customs. Lost 30 min in line when I had a short layover. Please update the help page with accurate information. It also has a bug where if the data is entered one day before the arrival, which is normal for overnight flights, it offsets the date-of-birth and passport expiration date by one day.
We’d never heard of this before our United Airlines flight attendant mentioned downloading the app and filling out your info on your flight home. You finish once you arrive at the airport. Super simple and saved us from sitting in the huge line of over an hour. We walked right up and skipped the line. I don’t know why 95% of travelers don’t utilize this free service.
I’ve flown international a few times and the customs lines are a drag to wait through. They take forever! The first review I saw was from a flight attendant that used this application. I decided to try it coming back from Ecuador into Miami. Was super easy. Just need your passport and know what terminal your flying into. I made it to customs and the lines were SOOOO long. I was with a group of 3 others. They didn’t download the app like I told them to and got stuck in a 2 hours line 😭. I was in line for maybe 5-10 minutes max. The global entry line was also a lot longer than the line I was in. I highly recommended using this app. It’s free and easy to use! So happy to have found a more convenient way of traveling now :)
Setting up MPC was pretty easy, and only took about 15 minutes to save 2 travelers. Instructions along the steps were clear, and there was ample reading material to help with the app process. Airport throughput was smooth at YVR, and we breezed through from arrival to gate in about 20 minutes. Thank you CBP for a very good product!! No crashes, glitches or freezes on my iPhone 12.
Among many issues with this app, there are several places in the app to report a problem, except that it doesn’t work. Every time I tried to submit a complaint / report a problem, I got an error. Without warning the app tried (and failed) to connect to my email to email my complaint. If you can only email a complaint, then state that in advance and provide the email address. Don’t try to hijack my email client on my mobile phone. Even better: accept a form like other apps and websites do, but provide the email as an additional option.
Downloaded the app and it didn’t work properly. The list of airports was blank for some reason, and I couldn’t select my port of entry. After many tries I decided to turn off my phone and on back again, and it finally worked. Then another problem, the submission of my form wouldn’t work, and it would time out. Had to try many different times until it finally did. Last but not least, the line was extremely slow, as the put together handicap passengers and MPC holders. I saw people in the regular line the came together with me being attended before I did.
The previous app worded well when the readers were working. This one seems to be the same thing but more user friendly. The Immigration officer stated they weren’t using it at Chicago. So he scanned all our passports then handed us a Customs form that he signed and stamped for the Customs officer. The Customs officer was good with the form from the other officer. If they ever get this working properly I will gladly use it and it will get 5 stars.
Forms are not required anymore at customs. It won’t let you submit with children for what sounds like human trafficking concerns. The time it took to fill this out was longer than the time with the border agent. We spend about 3 minutes with the border agent when we land in the US. I found the lack of clarity in why my forms were denied just frustrating and the app’s support team couldn’t give me a reason either apart from a hunch with trafficking. This doesn’t save you time waiting in customs - so why did it get developed at all?
This app should do a better job of pre screening before getting you to the end to do nothing. Poor user Interface needs work. Lots of wasted text clogging up path to where they want you to go. In the end one traveler was able to successfully complete while I was not. The edits are poor to non-existent so you have zero guidance and help along the way. I filled out the form and there was no path to continue. An absolute waste of my time. Whoever owns this needs to go through and end to end clean up if this disaster with thorough testing of more situations and map in the appropriate messages and edits.
This is way better than Global entry at SEA. Unlike Glovsl entries, no need for interview nor any fees. Everything is so easy and simple. Down load the app which I get to keep in my cell phone. Each entry to US, just answer quick questions, take a selfie and get a receipt. No need to fill out the custom form. Best of all, no need to stand in line at immigration. Just show ur receipt and the passport! Best thing ever!
Mobile Passport Control (MPC) is an official application created by U.S. Customs and Border Protection that streamlines your CBP processing experience at select U.S. entry locations. Simply fill out your traveler profile, answer CBP inspection-related questions, and proceed straight to the “Mobile Passport Control” lane at the airport or seaport. MPC is a voluntary program which can be used by U.S. Citizens, Canadian Citizen Visitors, Lawful Permanent Residents, and Visa Waiver Program Visitors at any of the supported airport and seaport locations found on our website: https://www.cbp.gov/travel/us-citizens/mobile-passport-control MPC provides a more efficient, secure in-person inspection process for the CBP Officer and the traveler, and shortens overall entry wait times. MPC can be used in 6 simple steps: 1. Create a traveler profile using biographic information from your passport; You can create a profile for all eligible members in a family group. Your profiles will be securely stored on your device completely free to be used for future travel. 2. Select your method of travel, select your port of entry and terminal (if applicable), answer CBP inspection-related questions, certify the truthfulness and accuracy of your answers, and, upon arriving at your selected port of entry, tap the “Submit Now” button. 3. Capture a clear and unobstructed photo of each traveler (including yourself) that you added to your submission. 4. Once your submission is processed, CBP will send a virtual receipt back to your device. 5. Proceed to the MPC designated lane upon arrival and be prepared to present your passport and other relevant travel documents. Please note: MPC does not replace your passport; your passport will need to be presented to the CBP Officer. 6. The CBP Officer will complete the inspection. If further information is required, the CBP Officer will let you know.
