Skip to content Once you’ve received your Green Card, you’re officially a permanent U.S. resident – allowing you to work and live in the U.S. on a permanent basis. After five years of permanent residency, you become eligible to apply for U.S. citizenship, under certain conditions, if you so choose. Alternatively, you can maintain your status as a permanent resident by following the required guidelines as set by the U.S. Citizenship and Immigration Services.
