There's an alternative ~ that he was doing business in the US and invested the required sum (I believe it was $250,000 at the time) and got a business visa.But you've stated several times, including in this thread, that Jimmy Carter gave him his visa (which is what Rossi claims).
I guess you don't have a clue what you're talking about.
The US government has several ways of importing foreigners besides just letting them slip in through Arizona and Texas. http://travel.state.gov/visa/ covers most of that. There’s also a refugee or asylum system. Rossi became a US citizen, so how did he get in? Please read the following section about prohibited classes and tell us how it was Rossi could commit the string of crimes you say he commited and still get into the US, or, if he was already here, stay here: http://travel.state.gov/visa/frvi/ineligibilities/ineligibilities_1364.html
