What are the current challenges regarding visas and immigration for expats in Thailand amid the coronavirus situation?

Most countries except there own citizens. There are still many airlines flying.

Yes but people in phuket need to get to there embassy in Bangkok to go get letter.

My position is (as if that counted for anything with the U.S. Embassy) The Letter is a Win/Win situation for Thailand and the Tourist or Expat on a Multi-Entry Non O or B... The people who get to stay for 30 days to get through this shutdown will spend money that Thailand says they want and need... Win/Win.

Thai Immigration seems to think that serious overstayees may get to stay and that's a bad thing. Well Damn. Immigration can certainly tell the difference between legitimate tourists and Expats needing 30 days and absconders who have overstaying for years.

I did have a thought today...some Imm. I/Os don't want to take the pressure of us who are caught in the middle 'cause that pressure induces a bribe offer for the 30 days.

There's a catch... Î

This is going to be a big issue soon and people will have to be allowed to stay. Thailand might end up a bit of an expat refuge from corona if things somehow stay under control here.

Only if you get a letter stating you can’t travel from your embassy. Most embassies aren’t issuing those letters.

That's amazing, probably will be renounced soon.
