Choice of Immigration Office
Are you allowed to go to any Immigration office for all visa requirements or do you have to go to the one where you are located?
Just wondering how restrictive it is as my friend will be vising CM from Bangkok.
TLDR : Answer Summary
In Thailand, you must go to the immigration office that corresponds to your registered address or where your TM30 was filed. If someone is currently holding a visa extension based on employment, they need to cancel that at the office that issued it before applying for a Covid extension at the appropriate office.
