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
It is not possible to change a Non-Migrant B visa to a tourist visa within Thailand. Instead, you must exit the country. If your nationality allows for visa exemption, you can re-enter Thailand, although re-entry is at the discretion of the immigration officer. Ensure you check the details on your visa stamp, especially if you have an extension of stay based on the Non B visa, as it may complicate re-entry and future applications for long-term visas.
