Guide to U.S. Green Cards
12-13 minutes read
TL;DR
A green card is the common name for a U.S. Permanent Resident Card (Form I-551). It proves that the holder has lawful permanent residence in the United States.
Green card holders may live and work anywhere in the U.S. permanently, for any employer, without immigration-related restrictions.
Permanent residence is not the same as U.S. citizenship. Green card holders cannot vote in federal elections, may lose their status under certain conditions, and must carry their card at all times.
The main pathways to a green card are family-based sponsorship, employment-based sponsorship, the Diversity Visa Lottery, asylum or refugee status, and special immigrant categories.
Annual limits cap how many green cards can be issued each year. Employment-based green cards are capped at roughly 140,000 per year; family-sponsored preference categories at 226,000. Immediate relatives of U.S. citizens are not subject to any numerical cap.
A per-country cap limits any single country to approximately 7% of annual preference visa numbers. This creates long backlogs for applicants born in India and China in employment-based categories.
After five years of permanent residence (three years if married to and living with a U.S. citizen), most green card holders are eligible to apply for U.S. citizenship through naturalization.
The green card itself is typically valid for ten years and must be renewed, though permanent resident status itself does not expire.
What Is a Green Card?
A green card is the common name for the Permanent Resident Card, officially Form I-551. It is a wallet-sized plastic card issued by the U.S. Citizenship and Immigration Services (USCIS) that serves as evidence that the holder is a lawful permanent resident (LPR) of the United States.
The name comes from the card's original green color in the 1940s and 1950s. The card has changed appearance many times since then, but the name stuck.
Holding a green card means the foreign national has been granted the right to reside permanently in the United States, to work for virtually any employer without restriction, and to travel in and out of the country.
It is the last immigration status before U.S. citizenship, and for many people it represents the primary long-term goal of the entire immigration process.
Permanent residence is permanent in the sense that there is no expiration date on the status itself. However, the physical card must be renewed every ten years, and the underlying status can be lost through certain actions such as abandoning U.S. residence, committing disqualifying crimes, or failing to meet other statutory requirements.
What a Green Card Allows
Holding a green card grants a broad set of rights and subjects the holder to a corresponding set of obligations.
Rights and Benefits
Work for any employer: A green card holder may work for any U.S. employer in any role without immigration authorization from USCIS. There is no need for employer sponsorship, no need to renew work authorization, and no restriction on the type of job. This freedom to change employers without immigration consequences is one of the most significant practical advantages of permanent residence over work visa status.
Live anywhere in the U.S.: Green card holders may live in any state or city without restriction and may own property anywhere in the country.
Travel internationally: Green card holders may travel outside the United States and return. Absences of up to six months generally do not threaten status. Absences between six months and one year may raise questions about abandonment of residence. Absences of one year or more create a strong presumption of abandonment unless the holder obtains a re-entry permit before departing.
Sponsor certain family members: Green card holders may sponsor their spouse and unmarried children for family-based green cards. The ability to sponsor a broader range of relatives, including parents and siblings, becomes available only after naturalizing as a U.S. citizen.
Access to some federal benefits: Green card holders who have worked and paid into the Social Security system for sufficient quarters may receive Social Security and Medicare benefits. Access to other federal benefit programs depends on the specific program and how long the holder has held permanent residence.
Path to citizenship: After five years of continuous permanent residence (three years for spouses of U.S. citizens who remain married and living with the citizen spouse), most green card holders are eligible to apply for naturalization and become U.S. citizens.
Protection under U.S. law: Green card holders are entitled to due process protections, the right to a fair trial, and protection under U.S. federal and state laws.
Green Card Obligations and Limitations
Cannot vote in federal elections: Green card holders are not U.S. citizens and may not vote in federal, state, or most local elections. Voting illegally can result in removal and bars to future immigration benefits.
Must carry the card: Green card holders are required by law to carry their Permanent Resident Card at all times when it is available. Failure to produce it on request by an immigration officer can result in a misdemeanor charge.
Must file U.S. taxes: Green card holders are treated as U.S. tax residents and must file federal income tax returns reporting worldwide income, the same as U.S. citizens.
Must register for Selective Service: Male green card holders between the ages of 18 and 25 are required to register for the Selective Service. Failure to register can affect naturalization eligibility.
Must report address changes: Green card holders are required to notify USCIS of any change of address within ten days of moving.
Status can be lost: Permanent resident status is not unconditional. It can be lost through voluntary abandonment, extended residence abroad, certain criminal convictions, fraud in the original application, or removal proceedings initiated by the government. In the current immigration environment, maintaining careful compliance with residency and legal requirements is more important than ever.
Cannot hold most security-clearance federal jobs: Many federal government positions, particularly those requiring high-level security clearances, are restricted to U.S. citizens.
The Main Pathways to a Green Card
There is no single universal green card application. The pathway depends entirely on the basis of eligibility. The major categories are as follows.
Family-Based Green Cards
Family-based immigration is the largest source of green cards in the United States. The category is divided into two groups based on the relationship and the sponsor's status.
Immediate relatives of U.S. citizens are not subject to any annual numerical cap. This group includes the spouse of a U.S. citizen, unmarried children under 21 of a U.S. citizen, and parents of a U.S. citizen who is at least 21 years old.
Because there is no cap, once the petition is approved and all admissibility requirements are met, there is no waiting period for a visa number. This makes the immediate relative category the fastest family-based route.
Family preference categories cover more distant relationships and are subject to annual numerical limits, meaning eligible applicants must wait for a visa number to become available before completing the green card process. The four family preference categories are:
Category | Who It Covers |
|---|---|
F1 | Unmarried adult sons and daughters of U.S. citizens |
F2A | Spouses and unmarried children under 21 of lawful permanent residents |
F2B | Unmarried adult sons and daughters of lawful permanent residents |
F3 | Married sons and daughters of U.S. citizens |
F4 | Brothers and sisters of U.S. citizens |
The family-sponsored preference annual limit is 226,000 per year. Per-country caps apply, creating multi-year waits for some nationalities in certain categories.
Employment-Based Green Cards
Employment-based green cards are organized into five preference categories based on the level of skill, achievement, or investment involved. The annual limit for employment-based green cards is at least 140,000 per year.
No single country may receive more than 7% of the annual preference total, which creates significant backlogs for applicants born in India and China.
Category | Who It Covers | PERM Required |
|---|---|---|
Individuals of extraordinary ability | No | |
Outstanding professors and researchers | No | |
Multinational executives and managers | No | |
Advanced degree professionals and exceptional ability | Yes | |
EB-2 NIW | National interest waiver self-petitioners | No |
EB-3 Professionals | Bachelor's degree holders | Yes |
EB-3 Skilled Workers | At least 2 years of training or experience | Yes |
EB-3 Other Workers | Unskilled workers | Yes |
EB-4 | Special immigrants (religious workers, certain broadcasters, others) | Varies |
EB-5 | Investors creating U.S. jobs | No |
EB-1 categories and EB-2 NIW allow self-petitioning and bypass PERM labor certification. All other employment-based categories require an employer sponsor, and most require PERM. The EB-5 investor category requires a minimum capital investment of $800,000 in a targeted employment area or $1,050,000 elsewhere, along with the creation of at least 10 full-time U.S. jobs.
The Diversity Visa Lottery
The Diversity Visa (DV) Program, also called the Green Card Lottery, makes approximately 55,000 immigrant visas available each year to nationals of countries that have sent fewer than 50,000 immigrants to the United States in the prior five years.
This effectively excludes countries with high immigration rates, including India, China, Mexico, the Philippines, and several others.
Applicants must meet minimum educational or work experience requirements. Selection is random via computer draw. Selected applicants must still complete the full green card process, including admissibility reviews, medical exams, and consular or adjustment of status processing, before receiving a green card. All processing must be completed within the fiscal year in which selection occurred.
Asylum and Refugee Status
Individuals who have been granted asylum or admitted as refugees may apply for a green card after one year in that status. The application is filed using Form I-485 for those in the United States. Refugee and asylee green cards are not subject to the same annual limits as preference categories, though they are subject to separate numerical controls.
Other Pathways
Several additional categories exist for specific circumstances, including victims of certain crimes (U visa holders who meet requirements), victims of trafficking (T visa holders), survivors of domestic violence (VAWA self-petitioners), and individuals who have been continuously residing in the United States since before January 1, 1972 (registry provision).
Special immigrant categories cover certain religious workers, certain international broadcasters, certain Afghan and Iraqi nationals who assisted the U.S. government, and others.
How the Numerical Limits Work
Understanding the annual caps and per-country limits is essential for anyone navigating the employment-based or family preference categories.
Each fiscal year, Congress sets numerical limits on how many preference green cards can be issued. The FY2026 limits are 226,000 for family-sponsored preference categories and at least 140,000 for employment-based categories. These limits do not include immediate relatives of U.S. citizens, who are uncapped.
A per-country cap, set by INA section 202, limits any single country to approximately 7% of the combined annual family-sponsored and employment-based preference totals. For FY2026, this works out to roughly 25,620 visas per country. The cap applies based on country of birth, not citizenship.
When demand from a country exceeds its per-country share in a given category, a backlog forms. Applicants from oversubscribed countries must wait for their priority date, which is the date their petition was filed, to become current on the Visa Bulletin before they can complete the final green card process. The Department of State publishes the Visa Bulletin monthly, showing the current cutoff dates for each category and country.
The practical consequence is stark. An engineer born in Germany and one born in India, both with identical qualifications and petitions filed on the same day in the EB-2 category, face fundamentally different timelines.
The German-born applicant may complete the green card process within months. The Indian-born applicant may wait over a decade, because India's demand for EB-2 visas far exceeds its annual share every year.
Conditional vs. Permanent Green Cards
Most green cards are issued as full ten-year permanent resident cards. However, two situations result in conditional residence, meaning a two-year card that requires a follow-up petition to convert to full permanent residence.
Marriage-based conditional residence applies when a foreign national obtains a green card through marriage to a U.S. citizen or permanent resident and the marriage was less than two years old at the time the green card was approved.
The couple must file Form I-751 to remove conditions within the 90-day window before the two-year card expires. USCIS uses this process to verify the marriage is genuine and ongoing.
Investor-based conditional residence applies to EB-5 investors. The conditions are removed by filing Form I-829 within the 90-day window before the two-year card expires, demonstrating that the required investment was made and maintained and that the required jobs were created.
Failure to file the removal-of-conditions petition on time can result in automatic termination of permanent resident status.

The Green Card Renewal
The green card itself is typically valid for ten years and must be renewed using Form I-90. Permanent resident status itself does not expire when the card does, but an expired card creates problems for employment verification (employers must verify I-9 work authorization) and for international travel.
Renewal is strongly recommended well before expiration. Renewal processing times have increased significantly in recent years. USCIS recommends filing six months before the card expires.
The Path from Green Card to Citizenship
Most green card holders become eligible to apply for naturalization and U.S. citizenship after meeting the following general requirements:
Five years of continuous permanent residence (measured from the date the green card was approved, not from when it physically arrived in the mail). For spouses of U.S. citizens who remain married and living with their citizen spouse, the requirement is three years.
Physical presence in the United States for at least 30 months of the five-year period (or 18 months of the three-year period for qualifying spouses).
Continuous residence in the state or USCIS district where the application is filed for at least three months before filing.
Good moral character for the statutory period.
Passing the English language test and the civics test.
Taking the Oath of Allegiance.
U.S. citizenship offers several advantages that permanent residence does not: the right to vote, the ability to sponsor a broader range of family members, a U.S. passport, protection from deportation in most circumstances, and eligibility for a wider range of federal employment and benefits.
Frequently Asked Questions
How long does it take to get a green card?
It depends entirely on the pathway. Immediate relatives of U.S. citizens can complete the process in as little as several months once the petition is filed. Employment-based categories for most countries are currently available without a meaningful wait, meaning total processing can take one to two years.
For applicants born in India in EB-2 or EB-3 categories, the wait for a visa number alone can exceed a decade. Family preference categories for some relationships and nationalities carry waits of many years as well.
Can I lose my green card?
Yes. Permanent resident status can be lost by voluntarily abandoning U.S. residence, spending extended periods outside the United States without a re-entry permit, committing certain crimes, or having the status rescinded due to fraud or misrepresentation in the original application. Once removed from the United States, a former green card holder generally cannot reapply through the same pathway without addressing the basis for removal.
Is a green card the same as citizenship?
No. A green card grants lawful permanent residence, which is the step immediately before citizenship. Green card holders have most of the rights of citizens with respect to working and living in the United States, but they cannot vote in federal elections, hold most security-clearance government jobs, obtain a U.S. passport, or sponsor siblings or married children for green cards.
Citizenship also provides greater protection from deportation and cannot be taken away in the same manner that green card status can.
Can my family come with me when I get a green card?
Spouses and unmarried children under 21 of green card applicants are derivative beneficiaries who may be included on the same petition and receive green cards at the same time. They receive the same priority date as the primary applicant.
Children who turn 21 during the process may be protected from aging out in certain circumstances under the Child Status Protection Act, though the calculation is complex and should be reviewed with counsel.
