What documents are required for applying for a Non-Immigrant O Visa as a Trailing Spouse in Thailand?

Remember, you cannot apply for in-country Non-o trailing spouse to a foreigner who is legally working in Thailand until he is on 1 year extension.

I believe you need the following documents to get an in-country Non-O Visa Based on Being a Trailing Spouse or a One Year Extension of Stay Based on Being a Trailing Spouse. I believe the documents are similar:

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 spouse physically next to the applicant, and:

a. Their original passport and a copy of their data “picture” page, and their extension of stay or visa.

b. If an extension of stay has not been acquired, the same paperwork required for the spouse’s extension of stay.

5. The original, and a front and back copy of the marriage certificate. The certificate may need to be translated using an approved translator from the Ministry of Foreign Affairs.

6. [EDIT]: For employment, the documents from the employer. The employer will be familiar with the documents required.

7. 2x passport sized (4cm by 6cm) photos.

8. 1,900 THB processing fee for the extension of stay, 2,000 THB processing fee for the Non-O Visa

Different immigration offices have different requirements, and may include:

- A hand drawn map to the applicant’s residence.

- Pictures of the husband and wife in various locations in the residence.

- Rental contract if applicable.

- Witnesses who are familiar with the couple and can verify they live together.

For the extension of stay, there is an under consideration period. This may include an at-home visit by the immigration office to confirm the husband and wife are living together or interviews with neighbors. The immigration office will give a list of the documents required to bring to the immigration office when the extension of stay is closed out.
