I've tried to do an accurate copy of the handout to include improper grammar, spelling, punctuation, etc.
After receiving this document I sat at the desk and read it. I asked if I needed to go to Bangkok to get my letter from the embassy verified. I was asked if my bank book showed foreign transfers coming in. I responded that it did. Then I was told it was probably not necessary to go to Bangkok.
That was the only question that I asked.
Always be aware of requirement number 11, and remember, the immigration officer is the one who decides if you have documented your qualifications for an extension.
