The Green Card, Explained

What a green card is

A green card, formally a Permanent Resident Card (Form I-551), is the document issued by USCIS that proves you are a lawful permanent resident (LPR) of the United States. It is your evidence of status — not the status itself, which is a legal classification, but the document that demonstrates it.

Permanent resident status carries broad rights and a defined set of obligations:

• You can live anywhere in the U.S. and work for any U.S. employer, with no employer sponsorship needed once you have the card.
• You can travel internationally and return, subject to maintaining your U.S. residence.
• You can sponsor certain family members for their own green cards.
• You are eligible for U.S. citizenship after a qualifying period — usually five years, or three for those who obtained status through marriage to a U.S. citizen.
• You remain subject to removability for certain criminal convictions, immigration fraud, abandonment of residence, and other defined grounds.

The phrase "green card" is a common nickname; the document has not always been physically green, but the name has stuck.

Green card vs. visa

The terms are sometimes used loosely, but they refer to different things. A visa is issued by a U.S. consulate and allows you to travel to a U.S. port of entry and request admission. A green card evidences your status as a lawful permanent resident once you have been admitted.

An immigrant visa issued abroad leads to LPR status upon entry; the green card itself is mailed afterward. A nonimmigrant visa (B, F, J, H, L, O, K, etc.) authorizes a temporary stay for a defined purpose and does not grant permanent residence on its own. See our companion guide on U.S. visa applications for the nonimmigrant side.

The two application paths

Green card applications take one of two paths depending on where the applicant is when filing:

The choice between paths usually depends on factors outside the applicant's control — where they currently live, whether they have an underlying status to maintain in the U.S., whether their priority date is current, and similar circumstances. Each path has procedural advantages and disadvantages; counsel can help evaluate which fits a specific situation.

How long it takes

Green card timelines vary dramatically by category and by where you are filing from. Some cases move in well under a year; others take more than a decade. Three factors drive most of the variation:

• Whether you are subject to numerical caps. Immediate-relative family cases (spouses, minor children, and parents of U.S. citizens) have no numerical cap. Most other categories do, which means waiting for a visa number under the monthly Visa Bulletin.
• Your country of birth. Per-country limits create dramatic differences in wait times. Applicants from India and China face the deepest backlogs in most employment-based categories; many family preference categories also have significant country-specific waits.
• USCIS and consular workload. Field office and consulate caseloads vary; processing times for the same form can differ by months from one office to another.

A confident "your case will take X months" is usually a red flag. Honest timing estimates are ranges, with specific caveats about category, country of birth, and where USCIS is currently processing.

How much it costs

USCIS filing fees vary by form and category, and have been adjusted multiple times — most recently in significant fee increases that took effect in April 2024. Beyond filing fees, applicants typically face costs for the medical examination, document translations, biometrics, and (for employment-based cases) employer-side costs including labor certification and prevailing wage determinations.

Because the fee schedule changes periodically and applies differently across categories, the most reliable approach is to use the USCIS fee calculator when budgeting:

• USCIS fee schedule and calculator
• I-485 form page (current fees and instructions)

Filing fees are generally nonrefundable, which is one reason getting the case right the first time matters. For certain employment-based filings, the cumulative cost (filing fees, premium processing, attorney fees, employer-side costs) can run substantially higher than family-based cases.

Types of green cards

Permanent residence is granted under several broad categories:

• Family-based — through a qualifying relationship to a U.S. citizen or lawful permanent resident.
• Employment-based — five preference categories (EB-1 through EB-5) for workers with qualifying skills, experience, or investment.
• Humanitarian — refugees, asylees, VAWA self-petitioners, T visa holders (trafficking victims), U visa holders (crime victims), and other protected groups.
• Diversity Visa Program — historically up to 50,000 annually by random selection; currently suspended (see below).
• Registry — for individuals continuously present in the U.S. since before January 1, 1972.
• Special immigrants — religious workers, certain Afghan and Iraqi nationals who supported U.S. operations, special immigrant juveniles, employees of qualifying international organizations, and others.

Family-based in detail

Family-based green cards are issued in two streams that behave very differently.

Immediate relatives (no annual cap)

If you are the spouse, unmarried child under 21, or parent (where the citizen is 21 or older) of a U.S. citizen, you are an immediate relative. There is no annual numerical limit on green cards in these categories, so you do not have to wait for a visa number under the Visa Bulletin. Widows and widowers of U.S. citizens are also covered if they were married at the time of the citizen's death and meet other requirements.

Family preference (annual caps; backlogs)

Family members who do not qualify as immediate relatives fall into one of the family preference categories:

• F1 — Unmarried sons and daughters (21+) of U.S. citizens
• F2A — Spouses and unmarried children (under 21) of LPRs
• F2B — Unmarried sons and daughters (21+) of LPRs
• F3 — Married sons and daughters of U.S. citizens
• F4 — Siblings of U.S. citizens (where the citizen is 21+)

Each category has an annual numerical cap, and per-country limits further shape wait times. F4 waits can extend a decade or more, particularly for applicants from countries with high demand. Cousins, aunts and uncles, grandparents, and other extended relatives do not qualify under the family-based framework unless they have a separately-qualifying closer relative.

Financial sponsorship

For most family-based cases, the sponsoring relative files an Affidavit of Support (Form I-864) pledging to maintain the immigrant at or above 125% of the federal poverty guidelines. If the relative does not meet the income threshold, a joint sponsor can take on that obligation.

Employment-based in detail

Employment-based green cards are issued in five preference categories. Roughly 140,000 immigrant visas are available across all five each year combined, with per-country limits that produce significant backlogs for high-demand countries — particularly India and China.

Labor certification (PERM)

EB-2 and EB-3 cases typically require an employer-sponsored Labor Certification (PERM) before the I-140 petition is filed. The PERM process tests the U.S. labor market to confirm there are no qualified U.S. workers available for the position. EB-1 and EB-2 NIW cases do not require PERM.

Humanitarian categories

Several pathways exist for individuals fleeing persecution or facing harm.

Asylum and refugee status

For those fearing persecution in their home country based on race, religion, nationality, political opinion, or membership in a particular social group. Refugees apply from outside the United States; asylees apply from within. After at least one year in the U.S. as a refugee or asylee, the individual can apply for a green card.

VAWA (Violence Against Women Act)

Abused spouses, children, and parents of U.S. citizens or lawful permanent residents can self-petition for permanent residence under VAWA — without the abuser's knowledge, cooperation, or notification. VAWA applies regardless of gender. The protections include strict confidentiality under 8 U.S.C. §1367, which prohibits USCIS from disclosing case information to the abuser.

T visa — Human trafficking victims

For victims of severe human trafficking present in the United States. T visa holders may apply for a green card after maintaining T status for three years, or for the duration of the trafficking investigation/prosecution if shorter, and meeting other requirements including good moral character.

U visa — Crime victims

For victims of certain serious crimes who have suffered substantial physical or mental abuse and are cooperating with law enforcement. After maintaining U status for three years and meeting continuing presence and cooperation requirements, U visa holders may apply for a green card.

Special Immigrant Juvenile Status (SIJS)

For certain immigrant children who have been abused, neglected, or abandoned, where reunification with one or both parents is not viable due to abuse, neglect, abandonment, or a similar basis under state law. State juvenile court findings are a prerequisite.

Parole in Place for military families

Available to certain undocumented spouses, children, and parents of U.S. military service members (including active duty, veterans, and Selected Reserve). PIP itself does not grant a green card, but it removes some procedural barriers to adjustment of status for eligible family members.

Diversity Visa Program

The Diversity Immigrant Visa Program (commonly the "green card lottery") was established by Congress in 1990 to make up to 50,000 immigrant visas available annually to nationals of countries with historically low rates of immigration to the United States. Selection has historically been by random lottery; selected applicants then undergo standard background checks, vetting, and consular interviews before any visa is issued.

Registry and other paths

Registry (longtime residents)

Individuals who entered the United States before January 1, 1972 and have continuously resided since may apply for a green card through the registry provisions. The category requires good moral character, eligibility for naturalization, and the absence of grounds that would otherwise bar admissibility or trigger removability. Because of the cutoff date, registry affects relatively few current applicants — though periodic legislative proposals to update the cutoff have been discussed without enactment.

Other narrow categories

Cuban Adjustment Act applicants, certain American Indians born in Canada, employees of qualifying international organizations, and several other small categories cover specific situations. Most prospective immigrants will not fit these — but they are worth knowing exist if your situation is unusual.

The process step by step

The shape of a green card application is consistent across categories, with variations in forms and supporting documentation.

1. The underlying petition is filed

   I-130 for family-based; I-140 for most employment-based; I-360 for VAWA, special immigrants, and similar; I-526E for EB-5. For self-petition categories (EB-1A, EB-2 NIW), the applicant files their own petition.

2. USCIS adjudicates the petition

   Approves, denies, or issues a Request for Evidence. For employment cases requiring it, PERM labor certification typically happens before the I-140.

3. The applicant waits for visa availability

   For categories with numerical caps, the applicant waits for their priority date to become current under the monthly Visa Bulletin. Some categories permit concurrent filing of the petition and the green card application.

4. The green card application is filed

   Form I-485 for adjustment of status; Form DS-260 through the National Visa Center for consular processing. Sponsoring family relatives also file Form I-864 (Affidavit of Support) for most family-based cases.

5. Biometrics and medical examination

   Fingerprints and photograph at a USCIS Application Support Center (for adjustment cases) or as part of consular processing. Medical examination by a USCIS-designated civil surgeon or panel physician abroad.

6. The interview

   At a USCIS field office for adjustment cases; at a U.S. embassy or consulate for consular processing. Some categories may have the interview waived in certain circumstances.

7. Decision

   Adjustment cases approved result in a green card mailed to the U.S. address. Consular cases approved result in an immigrant visa stamped in the passport; the green card is mailed after entry.
