Permanent residency of the US is permanent. Permanent residents have the right to live and work in the US without restriction on a permanent basis. The identification which proves permanent residency status – the green card – is not. Permanent residents need to keep a green card with them at all times to prove their permanent residency and green cards are only issued for ten years and every ten years US permanent residents needs to go through the green card renewal process filing Form I-90.
