TOURIST VISA

I'm currently on a 3mth only visa from the US & recently received my Thai national passport in BKK.  

What's the best way to stay longer if I should decide after my 3mths is up?  

Leave the country & enter as a Thai national? Where's the quickest boarder run & back? Costs?

If I choose to stay longer, does that effect my entry back to the US with my US passport?

Answer summary

The original poster has a 3-month tourist visa from the US and recently acquired a Thai passport. They seek advice on extending their stay in Thailand after the visa expires. Responses from the community clarify that with a Thai passport, they can remain in Thailand indefinitely. It's recommended to leave Thailand using the US passport and re-enter with the Thai passport to avoid visa issues. The advice emphasizes the importance of using the same passport for entry and exit to prevent complications.

Remember, you can only "switch" passports (dual citizenship, dual passports) by Air

NOT via Land Borders as the immigration officers of Both countries on both sides of the Land Borders are going to require both Exit and Entry Stamps inside the same passport

so, fly out of Thailand on your current passport (U.S. Passport), then fly back into Thailand on your Thai Passport

Dca Dca after reading the article, I do NOT need to leave when my 90 days are up, correct? Am I reading this right? I just simply show my Thai ID & passport, when I leave BKK, correct?

Kim Prapavat Generally yes, but the name in your Foreign Passport needs to be the same name as in your Thai Passport

You say you have received a thai national passport, so ofcourse you can stay in Thailand forever.

You should clarify with the immigration office and not here on FB .....since u already have a thai passport u are now thai and can stay here forever without any issues....it would be better for u to use your US passport while entering the US

Jesper Ngiam Not forever as the current entry was with a US passport as explained above, an extension is required to avoid overstay

I think you need to exit Thailand on your US passport before your current visa expires..

Otherwise you will be listed as overstaying on the US passport so that could pose a problem in the future..

Then you can immediately re-enter Thailand using your Thailand passport and stay as long as you like..

Then when you eventually want to return to the USA then exit on your Thailand passport and enter the US on your US passport..

You’re Thai you can stay here forever if you want it’s your country

It won’t affect anything in the USA since that’s your country as well

Stay as long as you want in either country or stay out of either country as long as you want

I don’t think you have to do a border run since you’re a citizen and when you leave you depart Thailand on your Thai passport and enter the USA with your USA passport

Leave Thailand with US passport and re-enter with Thai passport. As a national, you can stay as long as you want.

If you now have a Thai passport, you can go to your immigration office and apply for a 1-year Thai Citizen extension. You can do that forever. But next time you leave it'll be much better to use your Thai passport when you return, that way you don't need to worry about visas.

What you do here has nothing to do with your entry to the US.

She did not enter Thailand as a Thai. She entered with a foreign passport. So she is in Thailand as a foreigner. Until she leaves and enters with her Thai passport, that is how she will be seen by immigration.

Ray Bingham If she exited on her Thai passport then she would be on overstay on her US passport

they still have biometrics, so yes, it would flag that she entered on a foreign passport.

@Brandon ***********

that is the only circumstance I can think of that applies to this situation. IMO it is more about the airlines checking her in than it is about Immigration - personally, I don't think she would have an issue exiting on her Thai passport..... would it flag her entry on a US passport? I don't know.

Some people were born overseas and can't gather the correct proof to claim their citizenship until they're already in Thailand. But that doesn't change the fact that once someone enters on a specific passport, that's how they are seen by immigration until they exit and enter with a different passport.

IMO (and I could be wrong) She is ALWAYS a Thai citizen - assuming she was born here - the passport is just an identity and travel document. Surely she could have entered Thailand with an expired passport?.....or have I missed something.
