File Immigration Form I-90 to renew green card in US.

[Nancy Mervin]

For a green card holder while permanent status is permanent, 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 most green cards are only issued for ten years and so you should renew green card. This means that every ten years US permanent residents need to go through the green card renewal process.
