They will still be required to enter into the lottery to win a green card just like every other immigrant. By the way, FYI, Mexicans are not allowed to enter for a green card.

You're confusing the "diversity lottery" by which foreigners from selected countries may apply for extra green cards (50,000, IIRC) over and above those normally granted, with the green cards given through the normal application process.

Think about it: if all green cards were given by lottery, and Mexicans were ineligible, then no Mexicans would get green cards. That's clearly not the case.

That's because I believe that route is the only way temporary workers are eligile for green cards. The normal process for those working in the United States to become an immigrant requires that they are permanent workers.
