How long does a green card remain valid before expiring?

A green card, officially known as a permanent resident card, typically remains valid for a period of 10 years before it needs to be renewed. This 10-year validity reflects the need for the U.S. Citizenship and Immigration Services (USCIS) to periodically reassess the status of a permanent resident, ensuring they continue to meet the criteria for permanent residency.

While the green card is valid for 10 years, it's important for holders to apply for renewal about six months before the card's expiration date. This ensures they maintain their status without any lapse in their residency eligibility. Though there are certain conditions under which a green card can be obtained for a lifetime (for example, through some forms of immigrant visas), the standard duration of validity for most green cards is indeed 10 years.
