They also gain access to various government benefits such as Medicare, Social Security, and certain educational assistance programs, though some rights (such as voting or holding certain government jobs) remain reserved for nationals. A Green Card generally remains valid for ten years and must be renewed if the holder continues to meet residency obligations. Conditional Green Cards, often issued to spouses or investors, last for two years and require additional paperwork to remove conditions before expiration.
