Guys, just got accepted in an acceleration program in Washington D.C. I'm braziliand and now I'm worried regarding what kind os visa should I get.<p>Do you know if I can establish a new company in US with the B-1 visa? If not what kind of visa should I got for?<p>Do you give any advice what should I do? I don't have much time, like a month and a few days to get it.
You are screwed. This is way way too little time to get your visa situation in order. Consult an immigration professional immediately to have any hope of success.
I'm an American that has lived abroad twice and spent time in over 50 nations.<p>You really waited to the last minute on this. Most visas take 3-9 months. I would suggest your best option would be to try to apply for a student visa. I think it's called F-1
Likely you can get a B1/B2 visa. You should be able to establish a US company with B1/2 visa, however you can't work for it.<p>* personal opinion only, not a legal advise.
