What should I know about the 90-day stamp on my spouse visa in Thailand?

A bit surprised and now informed happy camper.

1. A visa and an extension of stay are different legal documents. A VISA allows you to ENTER Thailand for a limited amount of time, and an Extension Of Stay allows you to STAY in Thailand for a limited amount of time. A VISA is (almost always) a full page sticker, and an Extension of Stay is a half-page stamp.

2. Visas come in single and multiple versions. ALL VISAS (Except for Non-OA and Non-OX, and Elite) allow a person to stay *no more then* 89 days. For a single entry visa, once you use it to enter Thailand, it will be stamped "Used". For a multiple entry visa, you can enter and leave as many times as you like, up to the "valid to" date.

3. When a person enters Thailand, they are given an "admitted to" stamp at passport control. This stamp is the stamp that tells a person how long they can stay in Thailand - NOT the validity of the visa.

4. To stay longer beyond the "admitted to" stamp, a person must APPLY for an Extension of Stay. Generally a person applies for an Extension of Stay that's relevant to the visa they used to enter Thailand (such as a One Year Extension of Stay based on Marriage to a Thai National).

5. ALL Extension of Stays are 1,900 THB, and acquired at the local immigration office. Different immigration offices may have slightly different requirements.

6. IF a person is on an Extension of Stay, and they need to leave and return, they will get a re-entry permit at the immigration office (or at some airports). The re-entry permit is 1,000 THB for single entry, and 3,800 THB for multiple entry, and is valid for the length of the Extension of Stay. This is *NOT* a "multiple entry visa".

A 1 year non-O made more sense pre-Covid when you could do border runs every 90 days.

There is no stay-one-year Non-O visa besides the OA (retirement), need to get the one year extension in country.

Any type of non-immigrant visa itself without -A or -X gives the visa holder (up to) 90days stay when the holder is allowed to enter Thailand upon arrival, regardless of the number of entries on the visa sticker. 1-year multiple entries visa is valid for 1 year to enter Thailand unlimited times for 365days. But the length of each entry stays the same.

Your options to stay longer right now other than leaving Thailand and back might be:

- apply for Covid extension (60days)

- apply for a family visit extension (60days) (be aware this may be limited once per visa, or once per entry)

- apply for 1-year extension based on being married to a Thai national

Now you can get a 2 month family extension with no financial requirements while your 400k season for two months.

I happened to me as well. I applied for a one year visa, showed the required bank account with money they wanted to see and got a single entry non imm O. Got 90 days on entry

It sounds like you entered on a Multiple Entry Non-O visa based on marriage to a Thai national. The Visa ("sticker") is valid for one year, and allows unlimited entry and exit from Thailand. On each entry, you are stamped in for 89 days. If you want to stay longer, you need to acquire a One Year Extension of Stay Based on Marriage to a Thai National, or other relevant extensions that may apply for you.

Did you get a stamp in your passport that says "One Year Extension of Stay Based on Marriage to a Thai National"?

Does your visa have "multiple" or "single" written on it?
