Still in Limbo about Covid options, hard to find clear information before I make a decision.

Still looking for clear information so I can make my decision to stay or leave the country.  Non O Volunteer visa on many covid extensions, hoping for one more before heading back.  I live up country that has a small immigration office that always waits for orders from Chiang Mai.  Have heard many conflicting ideas and reports and still not sure how to move ahead.  I am from the States and our Embassy will not provide a letter for any type of extension this way.  I really would rather not go fly during this time of nasal swabs, quarantines if positive, and extra stress.  Much appreciated in advance!
