I had applied for USA B1 visa twice and got rejected. In first attempt interview was over just in 2 minutes by asking what is purpose of going to USA. Second time he gone through with my all documents but after 20 mins he rejected without saying anything. This was Two years back and now if I want to apply again then what care should take as well is there any chance to get B1 Visa ? I have my company invitation and all supported documents.
