By the way, why is the knee-jerk reaction always to talk to a "competent attorney" for stuff like visas? There are dozens of guest worker visas for the United States. Just applying for any visa to the USA is sufficient cause for the State Department to deny you future visas for the rest of your life. That includes completely sincere and honest applications. They just consider the application for any visa to be evidence of your suitability for future entrance and they keep track of tiny details forever. It doesn't matter if your life circumstances have changed. If you've seen Brazil, you've met America's immigration bureaucracy. A good immigration lawyer can reduce the trouble. You should never even apply for a tourist visa to the USA without asking an immigration lawyer.
