Thought I would share my Thailand pass story:
Applied last night about 10pm Las Vegas Time. My QR code and approval were in my inbox this morning ( US time ).
Uploaded my passport, vaccine card ( Johnson & Johnson 1 and done ), and my Thai insurance card issued when I got my regular health insurance ( includes covid coverage, but not stated on my card ).
Wasn’t sure if I would need a letter from the insurance company or not. Turns out my card was good enough.
Unbelievably smooth and fast. I have read several folks here and there stressing over the Thai pass and thought I would share what worked for me.
