I will tell you, as someone currently neck-deep in U.S. immigration procedures, what everyone else who knows anything about U.S. immigration procedures will tell you: Meet the requirements, fill the forms out correctly, don't conceal anything, and all should be fine. Every time, and I mean every time, someone on Visa Journey posts about getting denied for any sort of visa, once pressed for information, it's always because they did something wrong or they did not meet the requirements, plain and simple. My husband was granted a tourist visa to the U.S. in 2009 in Buenos Aires. He had no Argentine family, no property, no car, no kids, just a job and bank statements. He's from a country still known for drug trafficking more than anything else, and was expecting all sorts of scrutiny because that's just how they're treated everywhere (don't get me started), but he got it, no problem. They asked him what they always ask-- What do you plan to do there, how long will you stay, nothing weird.
He renewed it this year in Bogotá and now it's good for 10 years. He printed out a bunch of stuff he thought he'd need, but they didn't want to see a thing. The process took 20 minutes.
So I repeat: Meet the requirements, fill forms out correctly and do what you're supposed to do. Leaving your righteous anger at the door also helps.
