Can I change my visa from visa exempt to a non-B visa while remaining in Thailand?

I was in Si Racha Immigration today. They said you can change visas without leaving the country. I had friends change a tourist visa to marriage visa without leaving thailand last year.

Leaving the country was the old rule several years ago.

Also I posted about banks closing where I am in Bang Saen-they are going to limit bank access only to mall areas here. Seems stand alone banks will close this weekend.

Thais get much more info on changes than we do. Take it for what it's worth.

Your school should be doing all the paperwork and have a relationship with the local authorities.

okay the short answer to this question is

YES it is possible to change from a 30 day visa exempt or a 60 day tourist visa entry OR a 30 day extension on one of those to an in country 90 day non-B visa.

You need to have at least 15 to 21 days left on your current stamp when you apply because depending on the office the application goes under consideration between 14 and 20 days before you go back and get the Non-B visa and a 90 day entry stamp inked in.

Get a JOB and have your employer give you the documentation to apply for the 90 day Non-B inside the country.

I had to leave personally and i own a business. However i am due for a checkin or new non b and am speaking to attorney on how to handle it. Ill keep you posted.

You mean you have a visa exempt stamp. VOA not available to US citizens. A B visa means you have to have a business of which there are a number of conditions, not least that you have to employ four Thai people. What business are you looking at?

I would like to know as well
