Want to say a big thank you for all of the sage advice and info in this group. I read through many posts to gather info before I applied for a METV in the U.S. through the DC embassy. It paid off because I received my METV within 2 days.
Some tips I would share - For the question on your flight info, you can only upload one document but I knew that I had to show my flight into BKK but also leaving and returning to Thailand, to support the need for a METV. So I included all flight info in one pdf that I uploaded.
For the bank balance info. I don't remember if they asked for 6 months of balances of $700+ but that is what I provided. The Embassy came back and asked for 6 months of $7,000 balance, so I provided it. I redacted my bank statements so that all that showed was the month end balance.
Info in this group also indicated that I would need a confirmation of employment. The online application did not ask for this info but the Embassy did ask for it, so you need to have it.
For accomodation - I showed hotel for 1st 15 days and they didn't ask for any addt'l info.
