Hi, i m on a non migrant b visa whici i need to change in a tourist visa. I am in chiang rai. What s the best way to do it ? Some people say i can just go to a border and come back ? How much is it ? How long does it take ?
Thank you for helping.
TLDR : Answer Summary
In Thailand, you cannot change a Non-Migrant B visa to a Tourist visa while inside the country. The best option is to exit Thailand, and if your country is eligible for visa exemption, you can return without a visa. However, it's at the discretion of the immigration officer whether you are allowed back in. If you have an extension of stay based on your Non-B visa, you must cancel that extension before applying for a new visa to avoid complications.
