Found this old thread online:

 

https://www.thaivisa.com/forum/topic/773044-what-are-the-current-visas-for-monks/ (sorry -- couldn't open it up in the app).

 

Is this info regarding non immigrant R visas for monks still current? If you ordain while on a tourist visa, how do you go about getting an "R"? -- would you have to leave the country to do so?

 

And then if you disrobe while on the "R" visa, what happens -- do you need to leave the country within a certain number of days?

Yes it is correct.

In most cases you would have to leave the country to get the non-r visa. With the correct paperwork it might be possible to do a change of visa status at Bangkok immigration.

Thanks, ubonjoe!
