Question about double passport/overstay
Hi everyone, I entered Thailand under visa exemption 1 month with my French passport. I am going to ask for my Thai passport (couldn't do it before in foreign countries).
Can I just stay in Thailand without extending my visa and leave with my Thai passport ?
I thought of leaving by land border and re-enter with the Thai passport but it is not possible now. Has someone ever entered with a foreign passport and left with a Thai passport ?
It should be a problem since the immigration would have my information from the French passport in their records like I never left Thailand. But do they check anything if you leave with a new passport? Seeking for advices now đđģ
TLDR : Answer Summary
The user inquired about staying in Thailand while holding dual citizenship, having entered on a French passport but seeking to obtain a Thai passport. Responses advised that they cannot remain illegally and recommended applying for a one-year extension of stay to avoid overstaying, using both their French passport and the proof of Thai nationality. It was also clarified that they cannot switch passports while in Thailand and must leave the country on their French passport before returning with the Thai passport.
