A green card is the commonly used term for lawful permanent residency in the United States. It represents long-term authorization to live and work in the country rather than temporary entry or short-term permission.

The phrase “green card” is widely recognized, but it refers specifically to U.S. immigration status. While many countries have permanent residency systems, the term itself is not global.

In short: A green card is the commonly used name for U.S. permanent residency, allowing long-term living and working in the country.

What a Green Card Allows

  • Live in the United States long-term
  • Work without a separate permit
  • Travel in and out of the country within limits
  • Build toward long-term immigration stability

It does not grant full citizenship rights and still carries conditions.

How It Differs from a Visa

A visa is typically temporary. A green card represents long-term residency status rather than short-term entry.

How It Differs from a Work Permit

A work permit allows employment under specific conditions. A green card generally includes broader and more flexible work authorization.

Global Context

  • UK residency documentation such as BRP
  • Canadian permanent resident status
  • Other national residency systems with different terminology

This helps explain why “green card” should not be used as a universal term.

Common Misunderstandings

  • It is not citizenship
  • It is not a generic global term
  • It is not simply a long visa
  • It does not grant unlimited rights
Key takeaway: A green card is the U.S. term for permanent residency, providing long-term permission to live and work, but not full citizenship.
