On our (my wife and I) trip to room 303 we made it to the info desk there only to find out we didn't have the required documents to change from a tourist to a non-o. Got all the paperwork done, within the 21 day period, only to have a heart attack (no kidding) the night before going to immi. Needless to say we missed the 21 day window yet again, but I thought I would get the requirements to change from a tourist to a non-o (To fulfill the duty of responsiblity as an immediate member of a foreign family in Thailand)
1. - Application of Visa Status Alteration (TM 86)
- Application for visa
2. - Copy of passport
3. - 4 x 6 cm photo
4. - Application fee of 2000 baht
5. - Passport and work permit
6. - Certified copy of registration papers of the educational institution.
7. - Certified copy of the license of the school or university
(6 and 7 are not required if you are working at a government school)
8. - Certified letter from the school that you are working there
9. - Documents proving the relationship between the family members (marriage certificate, birth certificate, etc.) . If these are not from Thailand, they need to be translated into Thai and certified by the Ministry of Foreign Affairs.
10. - List of personal income tax of the Thai employee (for Thai's)
11. - List of personal income tax for alien employee (form 91) for the last year.
Hope this provides some useful info.
