American passport holder, here on visa exempt extention. I will be reaching my 180 day limit on tourism related visas for the year in a couple months. I am interested in staying past then to study muay thai. Can someone please explain how I would switch from the visa exempt to a ED visa for muay thai study? And are there general time limits for the program of study for muay thai ED visa? I am looking at local gyms currently. I live in a rural area of Ang Thong province.

My experience switching from Non O-A visa to Non O extension at Phuket immigration.

When my admittance stamp based on O-A was finished I left Thailand and returned on a 90 day Non O visa issued in my home country. I collected the handout from immigrations in Phuket and followed that instruction step by step. I used the German consulate (Phuket) affidavit as financial proof.

I attach the latest handout dated September 2022.

All went smooth and I "sailed thru" without problems.

Does anyone know the process of changing/switching a non-immigrant B visa to a non-immigrant O marriage visa? This would be while on a work permit

Good day .

I would like to ask is it possible to switch from a tourist visa to a non b visa ?
