Most people who become U.S. lawful permanent residents qualify through one of four doors: a family relationship, a job or investment, humanitarian protection, or the diversity visa lottery. A smaller set of special programs covers everyone else, from religious workers to certain juveniles. Which door you use determines the forms you file, whether an annual quota applies, and how long you wait.
This guide maps the main categories, explains how sponsorship and numerical limits work, and points you toward the next article to read for your situation.
Key takeaways
- Nearly every green card case is a two-step process: an approved petition first, then an immigrant visa or adjustment of status.
- Immediate relatives of U.S. citizens — spouses, unmarried children under 21, and parents — face no annual cap; most other categories do.
- Employment-based cases run through five preference levels, EB-1 through EB-5, most of which need an employer sponsor.
- Refugees and people granted asylum can apply for a green card after one year of physical presence in the United States.
- The diversity visa lottery makes up to 55,000 immigrant visas available each year to nationals of countries with low recent U.S. immigration.
How sponsorship and annual limits shape every case
With few exceptions, you cannot simply apply for a green card on your own. Someone — a relative, an employer, or occasionally you yourself — files a petition that establishes you fit a category. For family cases that petition is Form I-130; most employment cases use Form I-140.
Approval of the petition is not a green card. It only reserves your place in line. Congress caps most categories each year and also limits how many visas can go to nationals of any single country. The Department of State tracks demand in its monthly Visa Bulletin, and your "priority date" — generally the date the petition was filed — controls when you can take the final step.
That final step happens one of two ways: filing Form I-485 inside the United States, or attending an immigrant visa interview at a U.S. consulate abroad. The differences between them are significant enough that we cover them separately in adjustment of status versus consular processing.
Practical note: A category with no backlog today can develop a multi-year wait, and vice versa. Before making plans around a filing, check the current Visa Bulletin rather than relying on wait times you read about even a year ago.
Family-based categories: immediate relatives and preference lines
Family sponsorship splits into two very different tracks.
Immediate relatives of U.S. citizens — a spouse, an unmarried child under 21, or a parent (if the citizen is at least 21) — have no annual limit. A visa number is always available, so the timeline is driven only by processing speed. Spousal cases are the most common; see our detailed guide to the marriage-based green card process.
Family preference categories cover more distant relationships and are capped, which produces waits ranging from a couple of years to more than two decades depending on the category and country.
| Category | Who qualifies | Annual limit? |
|---|---|---|
| Immediate relative (IR) | Spouse, unmarried child under 21, or parent of a U.S. citizen | No cap |
| F1 | Unmarried adult sons and daughters of U.S. citizens | Capped |
| F2A | Spouses and unmarried children under 21 of permanent residents | Capped |
| F2B | Unmarried adult sons and daughters of permanent residents | Capped |
| F3 | Married sons and daughters of U.S. citizens | Capped |
| F4 | Brothers and sisters of adult U.S. citizens | Capped |
Two details trip people up. Marriage moves a beneficiary between lines — an F1 beneficiary who marries drops to F3, and a permanent resident's child who marries loses eligibility entirely until the sponsor naturalizes. And grandparents, aunts, uncles, and cousins have no sponsorship category at all.
Employment-based categories: EB-1 through EB-5
Employment-based immigration allocates visas across five preference levels. Most require a sponsoring employer, and the first three usually follow the sequence described in our guide to the PERM, I-140, and adjustment process:
- EB-1: people with extraordinary ability, outstanding professors and researchers, and multinational executives or managers. Some EB-1 applicants can self-petition.
- EB-2: advanced-degree professionals and people of exceptional ability, including self-petitioners seeking a national interest waiver. The tradeoffs between the top categories are compared in EB-1 versus EB-2 NIW.
- EB-3: skilled workers, professionals with bachelor's degrees, and certain other workers.
- EB-4: special immigrants, including religious workers and certain long-serving U.S. government employees abroad.
- EB-5: investors who put a qualifying amount of capital into a U.S. enterprise that creates jobs.
Country-of-birth limits matter enormously here. Applicants born in high-demand countries can wait many years even in categories that are current for everyone else.
Humanitarian paths to permanent residence
Several categories exist to protect people rather than to reunite families or fill jobs.
Refugees admitted from abroad and people granted asylum in the United States may apply for a green card after one year of physical presence. The asylum system itself — protected grounds, the one-year filing deadline, and evidence — is covered in our article on seeking asylum in the United States.
Other humanitarian routes include self-petitions under the Violence Against Women Act for abused spouses, children, and parents of U.S. citizens or permanent residents (open to applicants of any gender), green cards for victims of human trafficking with T status, and for crime victims with U status who helped law enforcement. Each has its own eligibility rules and waiting periods.
The diversity visa lottery
Congress sets aside up to 55,000 immigrant visas a year for nationals of countries with historically low U.S. immigration. Entry is free during the annual online registration window, but selection is only an invitation to apply — selectees must still prove they have at least a high school education or qualifying work experience, pass all admissibility screening, and complete the case before the fiscal year ends, or the chance is lost.
Selectees pay a per-person diversity visa fee at the interview stage (listed by the State Department at $330 as of August 2026). Because far more people are selected than there are visas, acting quickly after selection matters.
Special programs, registry, and everything else
Beyond the big four doors, narrower provisions cover specific groups: special immigrant juveniles who have been abused, abandoned, or neglected; certain international broadcasters and NATO employees; Afghan and Iraqi nationals who worked for the U.S. government; and Cuban natives under the Cuban Adjustment Act, among others.
There is also "registry," a little-used provision allowing people who have lived continuously in the United States since before January 1, 1972 to apply for permanent residence.
Figuring out which category fits — and whether more than one does — is often the highest-value question in a case, and a consultation with a green card attorney early on can prevent years lost to filing in a slower or weaker category.
Frequently asked questions
Can I apply for a green card without any sponsor?
In limited situations, yes. EB-1 extraordinary-ability applicants, EB-2 national interest waiver applicants, VAWA self-petitioners, and diversity visa selectees do not need a family member or employer to file for them. Most other categories require a petitioner, and the petitioner must generally also show the ability to financially support you or employ you.
How much does a green card application cost?
It depends on the path. As of August 2026, USCIS lists Form I-130 at $675 on paper ($625 online) and Form I-485 at $1,440; consular cases pay State Department fees instead of the I-485 fee. Always confirm current amounts on the USCIS fee schedule (Form G-1055) before filing, because fees change.
What is a priority date?
It is your place in line for a capped category — generally the date your petition (or labor certification) was filed. Each month the State Department's Visa Bulletin announces which priority dates are "current," meaning a visa number is available. Immediate relatives of U.S. citizens skip this system entirely because their category has no cap.
Does a green card expire?
The card itself is typically valid for ten years and must be renewed, but permanent resident status does not expire with the card. The exception is the two-year conditional card issued in newer marriages and to certain investors, which requires a petition to remove conditions before it expires.
Can I hold a green card and live mostly outside the United States?
Not comfortably. Permanent residence assumes the United States is your home. Long absences — especially over a year, or a pattern of living abroad — can lead officers to find you abandoned your status. Reentry permits help for planned long trips, but frequent extended absences put the card at risk.
Choosing a starting point
Start by listing every plausible category: relatives who are citizens or permanent residents, employers willing to sponsor, humanitarian claims, and lottery eligibility. Then compare each on three axes — whether you qualify today, how long the line is, and what could go wrong in your particular history, such as prior overstays or old arrests.
From there, read the deep-dive guide for your leading option, and browse our immigration law hub for related topics such as what naturalization will require once you have held the card long enough.
