I’m planning a trip to Singapore with my 9-year-old son.
We reside in Japan (I am a U.S. citizen with a zairyuu card; my son is a dual citizen of Japan and the U.S.), and I want to know which passport of his I should use to book our airline tickets (because he has different names between the two passports), and which passport he should use for entry to Singapore and subsequent return to Japan.
Thanks!
