U.S. immigration law can be complex, and there is a lot of confusion about how it works. Immigration laws have many goals, including keeping families together, bringing skilled workers to the U.S., and protecting people from danger. Some laws allow people to stay for a limited time. Other laws allow people to qualify for permanent legal status.
