What are the options for extending a single-entry Non-O family visa in Thailand for an additional 3 months?

@Ady *****

Then you can get a 60 day extension of stay based on raising half-Thai child. All extension of stays are 1,900 THB.

The specific requirements depends on the immigration office, however expect the following:

1. The applicant’s passport and a copy of:

a. The data “picture” page.

b. The most recent visa (if applicable).

c. All entry stamps or extension of stay (if applicable) since arrival .

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 half-Thai child physically next to the applicant, 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 visiting half-Thai child, a copy of the birth certificate.

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

5. 1,900 THB processing fee.

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

- Copies of all passport pages.

There is no under consideration issued with this extension of stay.

There is no such thing as a 3 Month Non-O Family Visa. A Non-O visa can be issued for one of the following reasons for family purposes (if my memory serves me right):

- Marriage to a Thai national

- Marriage to a foreigner

- Raising half-Thai child

- Raising foreign child

- Being a parent to a foreigner on a valid visa.

Each one has different requirements.
