Dual Citizenship & Advanced Passenger Information

I am asking this question on behalf of my friend. He is a dual US/Canadian Citizen with NEXUS who lives in the Philly area. Next month, he is heading to Thailand with another friend of his for about three months. They will fly round trip together with KE YYZ-ICN-BKK. That trip includes a 2-night stopover in Seoul on the way to Bangkok and another 1-night stop on the way back to YYZ. That friend of his is based in YYZ, hence he chose it as the KE gateway so they can fly together.

My friend has already secured a Thai Multiple Entry Tourist Visa. The visa is on his US passport, not his Canadian one. He applied it from the Thai Embassy in DC for convenience purpose, rather than going to the much further one in Ottawa. When he enters his APIS into the KE website, should he be entering his US or Canadian passport? AFAIK, Canada does have APIS requirement and so does both Thailand and the ROK.

Scenario 1: He enters the CDN passport into his KE booking. The APIS sent to the Thai immigration will be the CDN one, not the US passport where his visa is located in one of the pages. Considering his length of stay in Thailand is beyond the 30-day visa exemption period, could KE @ ICN demand he show his Thai Visa when checking-in for the BKK flight? If that's the case and he shows the visa on the US passport, could the airline deny boarding since the APIS he provided reflects the Canadian passport? If check-in @ ICN concerning the visa proof turns out non-eventful, could he encounter problems with Thai authorities when he lands and hands to the immigration officer his US passport as it does not match with the APIS KE sent to them?

Scenario 2: He enters the US passport as the APIS into his KE reservation. On the way back when he checks-in for the return flight at ICN, the APIS KE sends to the CBSA reflects his US passport. When he arrives back in YYZ and scans his NEXUS card into the kiosk, could he land in hot water with the CBSA where they could deem this as a violation and revoke his NEXUS? As a CDN citizen, he is required to enter with his CDN passport.

Scenario 3: He enters the US passport as the APIS into his KE booking. During the middle or latter portion of his trip where he has already spent more than half or more of his time in Thailand, he calls KE reservation and ask them to change the APIS from the US to the Canadian passport. Is this possible?? Will airlines generally allow you to change passports on the APIS for tickets where several sectors have already been flown? In this case he would have already flown 50% of his ticket (2/4).

APIS can generally be changed. That said, I'm not sure how Thailand could possibly know from the APIS how long he would be staying.

I'm not an expert but APIS isn't usually the end all. I would travel on one passport consistently if that passport doesn't have any visa or travel restrictions (i.e. not being able to enter w/o visa). APIS is more of a problem if one of the countries you hold citizenship in does not allow dual citizenship (e.g. China, South Korea, etc).

IME, it doesnít matter from the Thai side. Iíve checked-in one passport on my flight to BKK and entered with passport from different country. The Thai inspection was uneventful. Neither passport were Thailand.

1) API is a requirement on the airline, not the passenger.

2) API is not always related to immigration checks - for example not in all EU countries (yet).

3) AFAIK, API is not a requirement for flights involving Thailand, where the other countries involved also don't require it.



Of course, where one or more countries on your itinerary do require API, it will need to be collected before you can check in.

But, if you don't submit API yourself, the airline will just collect it when you present yourself for the flight, by swiping your passport. And it's much easier for a machine to read the MRZ of your passport(s) and fill in the data automatically, than to have to type in the information yourself - especially if you haven't memorized your passport information!

If you don't particularly care about checking in as soon as possible (T-24, T-48, or even at time of booking depending on airline) then you might as well save yourself the bother. If you need to check-in ASAP because you want to choose a seat, or because your airline has a history of overbooking and bumping the pax who were latest to check in, then obviously entering a few fields of data is not particularly difficult.

On the itinerary mentioned in the OP, it really doesn't matter which passport is used! If the airline is unhappy, they will just ask to see the other passport, and if the API needs to be altered it will be done by the check-in / gate agent.



I occasionally transit Thailand, on separate tickets, when flying between my countries of citizenship (A and B). On the flights to and from A, I check-in with passport A. On the flights to and from B, I use passport B.

I only enter Thailand with passport A. Nothing ever comes up at Thai immigration when going to/from B. Sometimes at BKK check-in, I present passport B for my flight to B, and they will ask why there is no Thai entry record. I then show passport A, and that's the end of the matter.

Sometimes, the API for my flight to B contains passport A's info because it is a through ticket from A. Country B doesn't seem to care about this, provided that I enter B with its passport.

Just use his US passport for everything including APIS, except when coming through immigration back into Canada. There is no requirement to leave Canada on a Canadian passport, and US citizens don't need a Visa or ETA to fly to Canada (on the off chance the airline asks about about why he only has a one way ticket to Canada with a US passport, he can show them his Canadian passport) .
