I actually know that it is possible to get an H-1B for a legitimate business that you, as a foreign entrepreneur, founded. I also know that such applications are very rare and very thoroughly scrutinized to make sure it's not an immigration loophole, and there is the restriction that you cannot be a majority shareholder, which kills it unless you have partners.

Less known is that a person can also sponsor you for an H-1B if you are going to be working for them.
