The interview at the Embassy was smooth, the consul was a very nice person, she doesn't ask me for more evidence and only ask me a few questions like, how do you met? how many times you entered to the US before and she told me that she needs to canceled my tourist visa because I can't have 2 visas at the same time and then YOUR VISA IS APROVED!!! Now I have to wait to pick up my passport with the visa at DHL one week!
