Thailand Non-Immigrant O Visa (Single Entry)

Validity of Visa: When you are issued a Non-O visa (single entry), it's usually valid for 90 days from the date of issue. This means you must enter Thailand within those 90 days.

Duration of Stay: When you enter Thailand using that visa, you will be granted a 90-day stay, regardless of how many days are left before the visa expires.

Example:

Visa issued: 1 July

Visa valid until: 28 September (90 days later)

You enter Thailand: 27 September

Your stamp at immigration: 90 days from 27 September → so, until 25 December

✅ Key point: The validity period is only about how long you have to use the visa to enter. Once you're in, the 90-day stay starts from your date of entry.

Hi, am I right in thinking that 45 days before expiration is the earliest I can start my marriage visa extension?

Master of bad timing, my visa expires mid April and I’d really like to get the paperwork in, the wheels turning and head south of Chiang Mai early March.

Thank you and seasons greetings to all the admin, y’all do an amazing job. 🙏

Hi! A couple of questions: I can legally work with a non-b visa (90 days), or should I wait until I actually have the Working Permit?

Second thing: if I leave my job, do I still have the rest of the 90 days, or my non-B visa automatically expires? Thanks a lot!

Hello. I have a non-b visa but i am not in thailand at the moment (i have a re-entry permit). I noticed my work permit is about to expire next week. If i let it expire, does that automatically​ cancel my visa as well?

I have a work permit that expires mid-May and will be renewed while in Thailand. I also have my Non-B multi-entry visa that also expires in mid-May. I have just arrived in Thailand and will be here until early June. Normally, I've gotten a new non-B visa in my home country every year with the fresh renewed work permit, before the old visa expires. Is there any issue not applying for my new yearly Visa until I return home in June after the expiration of the enter-by date of the previous visa? I believe for work permits, you need to renew before the expiration date, but is there a similar rule for Non-B visas that are being approved based on the work permit?
