I have a Non O immigration extension (1 year) that expires Jan 21. I was thinking of just getting the DTV as I may not be able to renew the O visa as I did not have the 800k in my bank account for the first few months and hear you need to show 12 months of statements.

Can I apply for the DTV in the USA while still on my current O?

Anyone do this?

I may arrive back to Thailand before but maybe after Jan 21...

Does it take 15 days max to process a 6 month tourist visa? Does the process take longer outside home country? If one is not financially able to go to a near by country (hotel, food, processing fee, flight) the best would be to return to country of origin before last run?

Thank you.
