Naturalization is the process by which a lawful permanent resident applies for and is granted U.S. citizenship. U.S. citizenship is a legal status that offers many benefits and responsibilities, including the ability to vote in U.S. federal elections, serve on a jury, travel with a U.S. passport, and bring family members to the United States. Importantly, once obtained, U.S. citizenship cannot be abandoned or lost by spending extended periods of time outside of the United States (as is the case with permanent residence).
