Can I apply for a new visa from Thailand after my tourist visa expires?

It's possible to apply for certain visas while in Thailand after a tourist visa. Applicants need to visit their local Immigration Office to obtain a list of requirements for the specific visa they want. Non-B or Non-ED visas usually require documentation from an employer or educational institution, and it's essential to check whether the application can be submitted in-country or if it necessitates exiting Thailand first. Additionally, it's important to note that there are no Thai embassies within Thailand.
