I had Gemini write a letter that says I will cover all expenses related to his stay. I added my bank statements from the last 3 months with 16k each month with my name on the account. I also included a copy of my passport. I combined all those into a single PDF and he was approved the next day. They asked for additional information on mine about travel details, but if they don't ask i wouldn't add it. Only include what they ask for.
i wish I would known that when I asked. I was in Cambodia at the time and it would have been easy to go to the Thai embassy. I'm back in the states now. I'll just do it myself then.
they said we didn't meet any of the requirements for anything outside of a tourist visa. I provided our financial information which is actually higher than I stated.
