What rights does a green card bestow?
A “green card”, also known as an “alien registration receipt card” and as Form I-551 or its older version Form I-151, gives you the right to live and work legally in the U.S. and to travel freely outside the U.S. as long as you make the U.S. your permanent home, do not commit any deportable crimes, and report all income to the U.S. government.
