How can a foreign national gain Lawful Permanent Residence?

There are two primary ways a foreign national can become a lawful permanent resident: he or she is either sponsored by a family member whom already lives in the United States as a citizen or lawful permanent resident, or he or she is sponsored by an employer for a U.S. job that falls under a particular category. In some less common cases, foreign nationals may be eligible to register for the diversity lottery or may qualify as refugees/asylees for fear of persecution in their home country.
