My statement is direct towards goal oriented people who want to succeed and are willing to iteratively test their options until something works. Not failures who are unwilling to take a risk or work for a reward. If you can't get a credit card, then hitchhike and/or volunteer on a yacht or just be homeless and work day labor that doesn't check your record until you've saved up a chunk.
An individual who is capable of success is capable of tirelessly executing options until they find one that works. And that is possible. Staying in the US means you will never fully regain your civil rights if convicted of a federal crime. Leaving means you have the chance of having the full civil rights of a citizen, somewhere.
