Family Petition (Permanent Residency Application) 

The Family Petition (Permanent Residency Application) allows foreign nationals to live and work permanently in the U.S., offering rights similar to U.S. citizens. The process requires the filing of Form I-130 or I-140, and is complex because it depends on factors like demonstrating family ties, employment, refugee status, etc. It often requires extensive documentation and interviews. Despite its complexity, this is the main manner that foreign nationals can apply for permanent residency in the U.S.
