Real Question: Has the U. S. Embassy Bkk issued any "new" phrases in their letter for Thai Immigration purposes? ... That is have they inserted any language that would help an American Expat who has a Non Immigrant Visa O or B get a covid-19 Extension?
Note: This phrase below was in the March 21 US Embassy Bkk Health Alert...
"U.S. citizens normally resident overseas should avoid international travel".
Key words "normally resident". But AFAIK The US Embassy has not even inserted this phrase above into their "Letter".
The US Embassy also inserted the following set of phrases in the referenced Health Alert that covers Tourists...
"U.S. citizens normally resident in the U.S. but currently outside the U.S., i.e. tourists and other short-term travelers, should return while there are still transportation options available."
