Hello, I just had a question if a foreigner could obtain a tourist visa while an immigration visa in being processed? I'm living with my wife in Chile, but we eventually want to move back to the US, in the mean time we would like to visit my parents since she hasn't met them personally yet. Is it possible to file a immigration visa, and then travel as a tourist (through the VWP or other B-2 Visa) for a month or so?
