Luisette,
Congratulations on passing the NCLEX - that's the biggest hurdle! Right now, we're waiting on Congress to issue some more Green Cards for nurses. Hopefully, that will happen in the next few weeks.
With regards to finding a nurse recruiter, the best thing to do is go to our "nurse recruiter" page. We've got a list of over 100 recruiters. I can't really recommend one over another, but suggest that you pick a few that are based in a State where you want to work (although many work with hospitals across the country, all should have relationships with hospitlas in their hometown).
Pick several to contact - don't just go with the first you see. Ask plenty of questions. Since you have already passed the NCLEX, it shouldn't be difficult them to place you.
Good Luck!
