Direct Short Answer

A green card (officially, a Permanent Resident Card) is proof that a non-citizen has lawful permanent resident status in the United States. Permanent residents can live and work anywhere in the country, travel abroad and return, and usually apply for U.S. citizenship after five years, or three years if married to and living with a U.S. citizen. Most people get green cards through a close family member, an employer, refugee or asylee status, or the diversity visa lottery. The card itself must be renewed every ten years, but permanent resident status does not expire unless it is lost or abandoned.

Key Takeaways
  • A green card proves lawful permanent resident status, allowing permanent residence and work in the U.S.
  • Main paths are family sponsorship, employment, the diversity lottery, and refugee or asylum status.
  • Immediate relatives of U.S. citizens are not subject to annual visa limits.
  • The card must be renewed every ten years, but status lasts unless lost or abandoned.
  • Long absences abroad and certain crimes can cost a person their permanent residence.

What a Green Card Means

Lawful permanent residents (LPRs) are non-citizens authorized to live in the United States permanently. The physical card, Form I-551, is valid for ten years (two years for conditional residents) and must be renewed, but the underlying status continues.

Rights of permanent residents

  • Live and work anywhere in the United States for almost any employer
  • Own property, attend school, and receive certain public benefits after waiting periods
  • Travel abroad and return, subject to rules on long absences
  • Petition for a spouse and unmarried children to immigrate
  • Apply for naturalization after meeting residence requirements

Responsibilities

  • Obey all federal, state, and local laws
  • File U.S. income tax returns and report worldwide income
  • Report a change of address to USCIS within 10 days (Form AR-11)
  • Register with the Selective Service if male and between 18 and 25
  • Carry proof of permanent resident status

Permanent residents cannot vote in federal elections. Falsely claiming U.S. citizenship or voting illegally can lead to removal.

The Main Paths to a Green Card

PathWho qualifiesKey notes
Immediate relatives of U.S. citizensSpouses, unmarried children under 21, and parents of citizens who are 21 or olderNo annual numerical limit
Family preference categoriesOther relatives, such as adult children and siblings of citizens, and spouses and children of permanent residentsAnnual limits; waits can be many years
Employment-based (EB-1 to EB-5)Workers with extraordinary ability, advanced degrees, skilled workers, special immigrants, and investorsAbout 140,000 visas a year plus unused family numbers; many categories need a job offer and labor certification
Diversity visa lotteryNationals of countries with low U.S. immigration rates who meet education or work requirementsUp to 55,000 visas a year, selected by random lottery
Refugees and asyleesPeople granted refugee or asylum protectionCan apply for a green card after one year
Special categoriesCertain special immigrant juveniles, religious workers, crime and trafficking victims (U and T visa holders), and othersSpecific eligibility rules

The worldwide limits are set by 8 U.S.C. § 1151 and the preference system by 8 U.S.C. § 1153.

The Application Process

Most green cards involve two stages:

  1. Petition. A relative files Form I-130 or an employer files Form I-140 (often after obtaining a Department of Labor labor certification). Some applicants, such as EB-1 extraordinary ability and EB-2 national interest waiver applicants, can petition for themselves.
  2. Visa availability. For categories with annual limits, applicants wait until their priority date is current in the State Department's monthly Visa Bulletin.
  3. Final step — one of two routes: - Adjustment of status (Form I-485) inside the United States, for applicants who are eligible to adjust (8 U.S.C. § 1255). - Consular processing at a U.S. embassy or consulate abroad, followed by entry on an immigrant visa.
  4. Biometrics, interview, and medical exam. USCIS or the consulate reviews eligibility and admissibility.

Conditional Residence

If a green card is based on a marriage that was less than two years old when residence was granted, the spouse receives a two-year conditional green card. The couple must jointly file Form I-751 in the 90 days before it expires to remove the conditions (8 U.S.C. § 1186a). Investor (EB-5) green cards are also conditional.

Travel and Abandonment

Long trips abroad can put status at risk:

  • Absences of more than six months may lead to questions about whether you abandoned residence and can break continuous residence for naturalization.
  • Absences of one year or more generally mean the green card can no longer be used to return, unless you obtained a reentry permit (Form I-131) before leaving.

How Permanent Residence Can Be Lost

  • Abandonment by living outside the U.S.
  • Removal (deportation) for certain crimes, immigration fraud, or other grounds of deportability
  • Rescission if the status was granted in error or through fraud

Permanent residents facing criminal charges should consult an immigration attorney before entering any plea.
