Green card is a document stating that a person is a lawful resident in the United States.

Permanent green card is valid for the period of ten years and can be renewed providing a lawful permanent resident did not commit any serious crimes in the past. There are conditional green cards given to persons who married U.S. citizens for the period of 2 years. If the marriage still lasts it can be converted to a permanent status.

It is important to remember that holding a U.S. green card (having a permanent residency in the United States) is not a right but a privilege. Green card holders have both rights and obligations, and under certain conditions green card status can be revoked.
