Hello everyone,

Quick question about passports and stamps:

So I have a Non-O retirement visa stamp + 12 moth extension stamp on my passport. I am from Finland and visiting Finland at the moment. I bought the re-entry stamp so everything is ok. Except that my pass port will expire within 9 months.

While still in Finland now, I got a brand new passport.

I cannot remember, which passport I now have to use when leaving Finland and enetering Thailand. Can you, please, remind me, is it the old one or the new one I have to use?

I know, I need to go visit the immigration office after I come back and they will move my visa + extension stamps to my new passport. But do they also move the entry stamps, hence my question earlier..?

Thanks in advance 👍

Answer summary

The user inquired about which passport to use when departing Finland and re-entering Thailand, given they possess a Non-O retirement visa stamp and an extension in an expiring passport while having obtained a new passport. Responses confirmed that the user should utilize the new passport for travel but also carry the old passport to show the stamps and re-entry permit upon entering Thailand. After returning, it's necessary to visit the immigration office to transfer the stamps to the new passport.

I recently got a new Australian passport, and in the fine print that came with it, advises me the old passport becomes invalid 30 days after the issue date of the new passport

, That totally depends on the country that issues the passport. Some countries void/invalidate the old passport at the time of issuing a new passport. Some do at the time of the new passport application.

hence why you carry both passports with you until new one is stamped correctly.

You use a new passport to both leave Finland and enter Thailand.

Make sure you show the old passport together when you enter Thailand, and be sure you are stamped in a new passport based on the re-entry permit in your old passport.

Once you are back in Thailand, bring both passports to the immigration office that issued your extensions to apply for the transfer of stamps to the new passport.
