The legal status of being authorized to work and remain in the U.S. indefinitely
Obtaining permanent resident status grants the person the legal right to live in the United States indefinitely. This does not mean the person has been granted U.S. Citizenship. A permanent resident must still have legal citizenship in another country.
Green Card
Obtaining a Green Card allows you to live and work permanently in the United States. The steps you must take to apply for a Green Card will vary depending on your situation. The application process for becoming a U.S. permanent resident is complicated, with many conditions determining your eligibility.
The best way to initiate the process is by retaining a U.S Immigration Attorney to assist you in the process.
