Hello, My two sons acquired their Thai citizenships well over 1 year ago. They have Thai passports and ID cards but have remained on a US visa (family visa) due to Covid and our inability to border bounce to cancel this US visa. We want to do a land crossing and we are in Chiang Mai. Is this possible for them to cross at Mai Sai (entering as a US citizen) and come back into Thailand as a Thai and what are the requirements or implications (any quarantines for Thais)? Any help or advise would be helpful. Thanks 🙏
TLDR : Answer Summary
The inquiry addresses the situation of two sons who possess Thai citizenship and hold Thai passports and ID cards but remain on a US family visa due to Covid-related travel restrictions. They are considering crossing the land border at Mai Sai as US citizens and returning as Thais. Respondents clarify that switching passports at a land border is not permitted; the family must fly out of Thailand on their foreign passports and return using their Thai passports. Additionally, there is discussion about visa extensions and the implications of being considered foreign nationals if they enter Thailand on a non-Thai passport.
