What options do I have for extending my Non O Spouse visa if my bank account balance won't meet the two-month requirement?

You can get a 60 day extension of stay based on visiting Thai family.

I don’t know what exactly is required at your immigration office, but expect the following:

1. Your passport and a copy of:

a. The data “picture” page.

b. The most recent visa (if applicable).

c. The most recent entry stamp or extension of stay (if applicable).

d. The departure card (“TM 6”) that should be stapled in the passport.

2. The extension of stay application form (“TM 7”).

3. A copy of the submitted Notification of Residence of Foreigners form ("TM 30”).

4. The Thai spouse physically next to you, and;

- Their Thai ID card and a front and back copy of the ID card

- Their housebook, and a copy of the first page.

5. For Thai spouse, a marriage certificate (either the rose border certificate, or a translated copy from the applicant’s home country), and a front and back copy of the marriage certificate.

6. 2x passport sized (4cm by 6cm) photos.

7. 1,900 THB processing fee.

Different immigration offices have different requirements, and this may include:

- Copies of all passport pages.

This will give you another 60 days in Thailand, added on to your current stamp.

Once you have 30 days remaining (45 days for some immigration offices), you can then apply for a one year extension of stay based on marriage.
