My wife has both British passport and Chinese passport with Japanese Residence Permit on her Chinese passport, and we are currently living in Japan. We are planning to go to South Korea next month, and I am Japanese passport holder which is visa free for enter Korea. My wife wanted to use her British passport to enter Korea due to visa-free too, and we also learned from other answers already:
- she would show her British passport to the airline counter in Japan to express that she can enter Korea without visa.
- then she would show her Chinese passport & Japanese residence permit to the immigration for exit Japan.
- arrival Korea and show her British passport to immigration to enter Korea.
Until now, I think there is no problem, if am correct?
My question is on her returning to Japan. Which passport should she show the airline counter? Since British passport and Chinese passport with Japanese Residence permit both can be valid to enter Japan. As I heard that airline will send passenger detail to destination immigration after check in (so if you check in with British passport you have to use the same passport to show the immigration, is this correct?), coz my wife would definitely use her Chinese passport with Japanese residence card to enter Japan, so should we have to show Chinese passport with Japanese residence card to airline counter? as China does not allow dual citizenship, so if we only show Chinese passport with Japanese residence card to airline counter, would the airline staff say your Chinese passport is not valid if they know she has dual passport? So, to be hassle free, can we just show airline only British passport to check in and arrive in Japan use her Chinese passport with Japanese residence card?
