A “green card,” issued by U.S. Citizenship and Immigration Services (USCIS), provides proof of lawful permanent resident status, with authorization to live and work anywhere in the United States. Most green cards must be renewed every 10 years, but conditional green cards based on marriage or investment must be replaced after the first 2 years.

U.S. Citizenship and Immigration Services (USCIS), part of the U.S. Department of Homeland Security (DHS), is the government agency that oversees legal immigration to the United States. USCIS is primarily responsible for approving green cards, naturalization, work permits, travel permits, and other “immigration benefits.”

A lawful permanent resident, also known as a “green card holder,” is a foreign national who is authorized to live and work anywhere in the United States, sponsor certain relatives for their own green cards, and ultimately apply for U.S. citizenship.

A conditional green card is valid for only 2 years, and the designation “CR1” on the physical card stands for “conditional resident.” A conditional green card holder must file Form I-751 to “remove the conditions” and obtain a permanent green card. In most cases, a conditional green card is issued to a spouse who has been married for less than 2 years at the time their green card was first approved.

A green card application may be denied by the U.S. government for several reasons, including but not limited to mistakes on the required forms, missing documents, insufficient financial resources, or failure to demonstrate eligibility.
