I have spent more than two and a half years filing forms and preparing paperwork for the U.S. government. I handled everything myself, without any “special” help or legal advice. I simply downloaded the forms from USCIS, filled them out using the required information, and submitted them.
What I can tell you is this: there is a massive market in the United States built on gray-area schemes, semi-legal shortcuts, and so-called expert advice. For example, there are companies charging $30,000 to submit a form that costs only $745 to file. Many “helpers” sell visa “upgrades.” The idea is that you arrive on a tourist visa and then follow a specific sequence of steps to convert it into a green card - something packaged and sold as a premium service for an extraordinary price.
This is a very large and lucrative slice of the pie that most people know little about. Both the U.S. visa process and tax filing system are riddled with gray practices and questionable “solutions.” Too often, the end result is that people are told to outright lie about their visa status or their taxes because they were instructed to do so.
From what I have observed, I would not call these practices outright foolish. Overblown at times? Yes, perhaps. But unnecessary? Not really.
