Definition
A green card is the common name for the Permanent Resident Card issued by U.S. Citizenship and Immigration Services (USCIS), the federal document proving that a foreign national is a lawful permanent resident. Holding a green card allows a person to live and work permanently in the United States. It conveys most, but not all, of the rights of citizenship and carries ongoing responsibilities to maintain that status under federal immigration law.
Legal Meaning
Immigration is governed entirely by federal law, primarily the Immigration and Nationality Act, and administered by federal agencies including USCIS, the Department of State, and the immigration courts. Unlike probate or business formation, which are matters of state law, green card eligibility and procedures are the same nationwide; there is no state-by-state variation in who qualifies for lawful permanent residence.
"Lawful permanent resident" (LPR) is the legal status, and the green card is simply the physical proof of that status. The term "green card" comes from the historical color of the card, which has changed over the years but kept the nickname. A permanent resident can generally remain in the country indefinitely, travel internationally with some limits, and work for most employers without separate authorization.
Permanent residence is not the same as citizenship. Green card holders cannot vote in federal elections, can lose their status in certain circumstances, and must continue to comply with immigration rules. Many later pursue naturalization to become U.S. citizens. Because the stakes are high and the rules are technical, the broader subject is explored further on our immigration practice area page.
Key Points
- A green card proves lawful permanent resident status; it is governed by federal, not state, law
- Permanent residents may live and work in the U.S. on a permanent basis
- Common paths are family-based, employment-based, refugee or asylee, and the diversity lottery
- Family- and employment-based categories have numerical limits and waiting lines
- The status is different from citizenship and does not include the right to vote in federal elections
- The physical card must be renewed periodically, but the status itself continues
- Conditional residents must file to remove conditions before their card expires
- Permanent residence can be abandoned or revoked, with serious legal consequences
Real-World Example
Maria is a U.S. citizen who marries Daniel, a citizen of another country. Maria files an immigrant petition for Daniel as her spouse. Because spouses of U.S. citizens are considered immediate relatives under federal law, a visa is available right away rather than after a long wait in a preference category.
Daniel applies to adjust his status because he is already in the United States, attends a USCIS interview, and is approved. Because the couple married recently, Daniel receives a conditional green card valid for a limited period. Before it expires, he and Maria must jointly file to remove the conditions and show their marriage is genuine. Once approved, Daniel becomes an unconditional permanent resident and may later consider applying to naturalize as a citizen.
Family-Based vs. Employment-Based Green Cards
| Feature | Family-Based | Employment-Based |
|---|---|---|
| Who sponsors | U.S. citizen or permanent resident relative | U.S. employer (or self in some categories) |
| Basis | Qualifying family relationship | Job offer, skills, or investment |
| Annual limits | Immediate relatives are unlimited; others are capped | Capped by preference category |
| Waiting line | Often long for non-immediate relatives | Varies by category and country |
| Labor certification | Not required | Often required for certain categories |
| Governing authority | Federal (USCIS / State Dept.) | Federal (USCIS / DOL / State Dept.) |
Main Paths to a Green Card
Federal law recognizes several routes to lawful permanent residence. The most common include:
Family Sponsorship
U.S. citizens and permanent residents may petition for certain relatives. Immediate relatives of citizens, such as spouses, parents, and unmarried minor children, are not subject to annual caps, while other family categories face numerical limits and waiting periods.
Employment
Employers can sponsor workers in several preference categories based on skills, education, or job needs. Some categories require a labor certification confirming that no qualified U.S. worker is available. A few categories allow individuals with extraordinary ability or investors to self-petition.
Humanitarian Categories
Refugees and people granted asylum may apply for a green card after meeting eligibility requirements. Other humanitarian programs exist for specific situations.
Diversity Visa Lottery
A limited number of green cards are made available each year through a lottery for nationals of countries with historically low rates of immigration to the U.S.
Most paths involve a petition, a wait for visa availability, and then either adjustment of status inside the U.S. or consular processing abroad. The specific steps, eligibility rules, and waiting times change over time, so applicants should rely on current official guidance and, when needed, professional advice.

Frequently Asked Questions
What is a green card?
A green card is the common name for a Permanent Resident Card issued by U.S. Citizenship and Immigration Services (USCIS). It proves that a foreign national is a lawful permanent resident who may live and work permanently in the United States. Green card status is granted under federal immigration law, not state law, and gives most of the rights of a citizen except the ability to vote in federal elections and hold certain government positions.
How do you get a green card?
Most people obtain a green card through a family relationship, an employer sponsor, refugee or asylee status, or the diversity visa lottery. The process generally involves an immigrant petition, waiting for a visa to become available under federal preference categories, and then either adjusting status within the U.S. or completing consular processing abroad. The right path depends on individual circumstances, so many applicants consult an immigration attorney.
What is the difference between a green card and citizenship?
A green card grants lawful permanent residence, while citizenship is full membership in the country. Permanent residents can live and work in the U.S. indefinitely but cannot vote in federal elections, can be subject to removal for certain offenses, and must maintain their status. Many permanent residents may later apply to naturalize as U.S. citizens after meeting residency and other eligibility requirements set by federal law.
Can a green card be lost or revoked?
Yes. Permanent resident status can be lost through abandonment, for example by living outside the U.S. for extended periods without taking steps to preserve residence, or revoked because of certain criminal convictions, fraud in obtaining the card, or other grounds of removability under federal immigration law. Because the consequences are serious, a permanent resident facing any of these issues should seek qualified legal advice promptly.
Does a green card expire?
The physical Permanent Resident Card typically must be renewed periodically, but renewing the card does not change your underlying permanent resident status, which generally continues until it is abandoned or revoked. Conditional permanent residents, such as some recent spouses of citizens or certain investors, receive a card valid for a limited period and must file to remove the conditions before it expires.
