@Mike ******
Thank you for the info. I have no problem leaving Thailand right before my 90 days, and I can book an onward ticket at the 60 day point in time.
I'm trying to complete all the requirements for the Thai e-visa by tonight/tomorrow, so I can still use either STV or TV.
My big concern is how long will the STV visa take to be approved since I leave San Francisco on November 28th?
If the TV is approved faster, then that is probably the only safe option left for me, and I can add an onward flight at the 60-day mark.
