I have a Non-Immigrant O-A visa, issued from my application filed in South Korea.

The visa is multiple entry.

The visa was granted 15-December-2023.

Visa must be used by 14-December-2024.

I am a USA citizen.

I am a permanent resident of South Korea.

My next trip to Thailand is scheduled for 1-December-2024.

My required Thai insurance certificate is valid until 25-December 2025.

OK.. The question. When I enter, my “visa” will be activated for one year (I assume until November 30, 2025). What about paperwork. Until now, I have had the Thai eVisa letter with the dates. If I leave in January for a trip home, what do I need to do?

Do I need to get another multi-entry stamp?

How does immigration know that my visa is valid until November 30, 2025?

How would I prove it when I re-enter the Kingdom AFTER my trip home in January?

Thank you for your help.

I am holding a non-OA retirement visa to be expired in Oct. As non- OA retirement visa requires insurance coverage with Thai insurance company which I have got accordingly. However, I have my own insurance with my home country, so the insurance in Thai is unnecessary and the premium is getting expensive. Therefore, I am thinking to get a non-O retirement visa to save the insurance premium for a long term.

If I leave the country before my current visa expires and return after the expiry date, then, apply a non-O retirement from scratch. Is it the right way to do it? Is there anything I need to be aware of?

Do I need any proof of onward travel given that I won’t have a long stay visa anymore?

I’ll have 30days visa free period when I enter the country, is it enough to get the visa approved within the time span?

TIA
