Can you convert a Tourist Visa, or a 30-day visa stamp (exemption), into a 90-day Non Immigrant O Visa?
Yes. Well, not so much convert, but immigration will cancel your current visa, or stamp, and issue the Non O, if you meet the requirements.
This visa can be issued on the basis of marriage to a Thai national, having Thai children, retirement or education purposes.
In this post, I’ll list the documents for those applying on the basis of being married to a Thai national, and for those applying on the basis of retirement.
After you submit the application, you must stay in Thailand for 15 days to await approval.
Please note: This is a 90-day, single entry visa (you have already entered). If you leave the country without a re-entry permit, your visa will automatically be cancelled. This is not a multiple entry visa, meaning you cannot come and go as you please.
It is also NOT a 1-year…
