The main routes to a green card and who qualifies for each
A green card (officially a Permanent Resident Card) gives you the legal right to live and work in the United States permanently. There is no single path to one. Instead, the U.S. immigration system offers several routes, and which one you can use depends on your situation: whether a U.S. employer will sponsor you, whether you have family members who are U.S. citizens or permanent residents, whether you are fleeing persecution, or whether you have extraordinary ability in arts, sciences, business, or athletics.
Each route has different requirements, different timelines, and different costs. Some require a job offer first. Some require a family relationship. Some are based on humanitarian grounds. Understanding which category fits your situation is the first step, because you cannot move forward until you know which door you are walking through.
Key Takeaways
- Green cards are issued through family sponsorship, employment sponsorship, diversity visa lottery, refugee or asylee status, or special categories like victims of trafficking or crime.
- Family sponsorship requires a U.S. citizen or permanent resident relative to petition for you, and processing times range from months to years depending on your relationship and country of origin.
- Employment-based green cards require an employer to sponsor you and usually require proof that no U.S. worker is available for the job, a process called labor certification.
- The diversity visa lottery is free to enter and draws 50,000 winners annually, but winners still must meet health and background requirements before receiving a green card.
- Refugee and asylee routes exist for people fleeing persecution, and asylees can adjust to green card status after one year in the United States.
Family-based green cards: who can sponsor you and how long it takes
If you have a close relative who is a U.S. citizen or permanent resident, they can petition for you. The relationship must be one the law recognizes: spouse, parent, child, or sibling of a U.S. citizen; or spouse, child, or parent of a permanent resident. More distant relatives cannot sponsor you.
A U.S. citizen can petition for a spouse, parent, or child at any time. A permanent resident can petition only for a spouse or child. The petitioner files Form I-130 (Petition for Alien Relative) with U.S. Citizenship and Immigration Services (USCIS). If you are already in the United States, you can file Form I-485 (process to Register Permanent Residence or Adjust Status) at the same time. If you are outside the United States, you wait for the petition to be approved, then go through consular processing at a U.S. embassy or consulate in your home country.
Processing times vary widely. when ready relatives of U.S. citizens (spouse, parent, child under 21) typically see decisions within months to a year. For siblings or adult children of U.S. citizens, or for any relative of a permanent resident, there is a waiting list called the preference system, and wait times can be several years depending on your country of origin and the current visa bulletin published monthly by the State Department.
Employment-based green cards: what employers must do and what you must prove
An employer can sponsor you for a green card if they want to hire you permanently. The process differs depending on the type of job and your qualifications. Most employment-based green cards fall into one of five preference categories, ranked by skill level and education.
For most jobs, the employer must first file a labor certification with the Department of Labor. This means they must advertise the job to U.S. workers and document that no U.S. worker is available or willing to do the job at the offered wage. This step alone can take six months to two years. Only after labor certification is approved can the employer file the I-140 petition (Immigrant Petition for Alien Worker) with USCIS. Once that is approved, you file I-485 to adjust status or go through consular processing.
Some jobs skip labor certification. These include positions requiring an advanced degree in a specialty occupation (called EB-2 with a National Interest Waiver), positions for individuals with extraordinary ability, and positions for certain multinational executives or managers. Even without labor certification, the overall timeline from job offer to green card in hand is typically two to four years.
The diversity visa lottery: free entry and 50,000 visas per year
The diversity visa program, often called the green card lottery, randomly selects 50,000 people each year to immigrate to the United States. Entry is free. You submit an online form during the annual registration period (usually October through November) with your name, date of birth, passport number, and a photo. The drawing is random.
If your name is drawn, you are notified by mail and given instructions to proceed. You must then pass a medical exam, a background check, and an interview at a U.S. consulate. You must also show that you have a high school education or equivalent, or that you have worked in an occupation requiring at least two years of training or experience within the past five years. You cannot have a criminal record or certain health conditions.
The diversity visa is available only to nationals of countries with low immigration rates to the United States. If your country sent more than 50,000 immigrants to the U.S. in the previous five years, you are ineligible. The list of ineligible countries changes yearly and is published by the State Department before each registration period.
Refugee and asylee routes to permanent residence
If you are fleeing persecution based on race, religion, nationality, political opinion, or membership in a particular social group, you may be able to enter the United States as a refugee or obtain asylum.
A refugee applies for protection from outside the United States, usually at a U.S. embassy or through the United Nations High Commissioner for Refugees (UNHCR). The U.S. Refugee Admissions Program vets applicants and, if approved, brings them to the United States. An asylee applies for protection after arriving in the United States, either at a port of entry or by filing Form I-589 (process for Asylum and for Withholding of Removal) with USCIS if already in the country.
Both refugees and asylees can adjust to permanent resident status after one year in the United States. The process is simpler than other green card routes because you do not need an employer or family sponsor. You file Form I-485 one year after your arrival or approval as a refugee, or one year after your asylum grant. Processing typically takes several months.
Special categories: trafficking victims, crime victims, and others
The immigration system recognizes certain groups outside the main categories. T visa holders (victims of human trafficking) and U visa holders (victims of certain crimes who cooperate with law enforcement) can adjust to permanent resident status after three years. VAWA (Violence Against Women Act) petitioners—spouses or children of abusive U.S. citizens or permanent residents—can self-petition without the abuser's knowledge or consent.
These categories exist because the law recognizes that some people cannot use standard routes due to their circumstances. If you believe you fall into one of these groups, you should speak with an immigration attorney or contact a nonprofit organization that provides free or low-cost immigration legal services in your area.
What happens after your green card is approved
Once USCIS approves your I-485, you receive a green card in the mail within weeks. The card is valid for ten years (two years if you obtained it through marriage and have been married less than two years). You can live and work anywhere in the United States without needing employer sponsorship.
You must carry your green card with you at all times. You can travel outside the United States, but trips longer than six months may be viewed as abandonment of your permanent residence. If you plan to be outside the U.S. for more than a year, you can file Form I-131 (process for Travel Document) to request a re-entry permit before you leave.
You can explore for U.S. citizenship after holding a green card for five years (or three years if you are married to a U.S. citizen). Citizenship is not automatic—you must file Form N-400 (process for Naturalization) and pass an English and civics test.

Frequently Asked Questions
Can I work in the United States while my green card is being processed?
If you file Form I-485 (adjustment of status), you can request work authorization by filing Form I-765 (process for Employment Authorization) at the same time. USCIS usually approves work permits within two to three months. If you are going through consular processing outside the U.S., you cannot work until your green card is issued.
What if my country is not may be able to access for the diversity visa lottery?
You must use one of the other routes: family sponsorship, employment sponsorship, refugee or asylee status, or a special category. There is no alternative lottery or backup option. Your country's may be able to access is determined by immigration statistics from the previous five years and does not change during the year.
Do I need a lawyer to get a green card?
You are not required to hire a lawyer, but the process is complex and mistakes can delay your case or result in denial. Many nonprofits offer free or low-cost consultations. If you cannot afford a lawyer, contact your local legal aid society or search for immigration legal services in your area through the American Immigration Lawyers Association website.
What happens if my green card process is denied?
The reason for denial is explained in a letter from USCIS or the State Department. Some denials can be appealed; others cannot. If you are denied, you should consult with an immigration attorney to understand your options, which may include reapplying, appealing, or exploring a different route.
Can I lose my green card after I receive it?
Yes. You can lose permanent resident status if you commit certain crimes, abandon your residence by staying outside the U.S. for more than two years without a re-entry permit, or engage in fraud to obtain the card. You can also voluntarily surrender your green card. If you are concerned about your status, speak with an immigration attorney.
