B Sousa,
Not so. If you have a Degree in a field that is sought after in the US, you can get a H-1B Visa in 15 days - if someone has a need to employ you. There are also other relatively easy and legal ways to work in the land of opportunity. The US rewards those that are suitably qualified. However the system cannot cope with the flood of 'undocumented' workers, that is for sure.
Bugdevheli,
If you don't already have some sort of right to work here you will need a capable immigration attorney. PM me if you need a contact.
