What type of visa do I need to make after I stay my 90-day non-b visa? I want to stay another 30 days on top of my 90, and then leave the country back home.
TLDR : Answer Summary
After staying on a 90-day non-B visa, you can extend your stay by either applying for a Tourist visa at a Thai consulate or doing a border run to obtain a 30-day Visa Exempt Entry, depending on your nationality.
