a Nice discussion got deleted by the original poster. She just wanted to know about reporting her TM 30 after coming back from abroad with her tourist Visa, because she wanted to be legal in Thailand.
As we like to give advice to be legal, some people just looked at her Facebook page and came to the surprise that she was working inside Thailand.
So the comment came: To stay inside Thailand you need a Work Permit and the Non Immigrant B Visa.
This is NOT to attack you, stalk you or judge you.
I had the experience that Immigration Officer checked my Facebook when I applied for an Extension of Stay. And I know that almost every person in Thailand has a smart phone and lots of them have a profile on Facebook. Strangely enough, even when we foreigners think it is, Facebook and internet is not limited for foreigners, even Police, Immigration and Ministry of Labor staff have profiles and use Facebook on daily basis. People go in jail for selling drugs, guns, gems or other scams using Facebook profiles, just because Police is checking profiles. Be careful what you write down on your own profile specially if you decide that Thai labor and Immigration laws are not for you. If you get an answer get the Work Permit and correct Visa it is not judging your lifestyle, but a warning, because: If we can read it, Thai officials will read it.
