What a Green Card Is and the Main Routes to Get One
A green card is a document that lets you live and work permanently in the United States as a lawful resident. It is not citizenship — you do not vote or hold a U.S. passport — but it gives you the right to stay indefinitely, work for any employer, and travel in and out of the country. You get a green card through one of several paths: a job offer from a U.S. employer, family sponsorship, diversity visa lottery, refugee or asylee status, or special categories like investor visas or religious worker visas.
The path you take depends on your situation. If a U.S. employer wants to hire you, they sponsor you. If you have a close family member who is a U.S. citizen or green card holder, they can sponsor you. If you are from a country with low immigration to the U.S., you may enter the diversity visa lottery. Each route has different timelines, costs, and requirements.
Key Takeaways
- A green card lets you live and work permanently in the U.S., but you must obtain it through one of several legal pathways — employment, family sponsorship, diversity lottery, or refugee status.
- Employment-based green cards require an employer to sponsor you and prove no U.S. worker is available for the job, a process that typically takes two to three years.
- Family sponsorship is faster for when ready relatives of U.S. citizens (spouse, parent, child under 21) but can take many years for other relatives depending on visa availability.
- The diversity visa lottery is free to enter and draws 50,000 winners per year, but you must be from an may be able to access country and meet education or work experience requirements.
- Processing times and costs vary widely by category and your country of origin, so understanding your specific path early saves time and money.
Employment-Based Green Cards
An employer sponsors you for an employment-based green card by filing a petition with U.S. Citizenship and Immigration Services (USCIS). The employer must show that they need someone with your skills and that they have tried to hire a U.S. worker at the prevailing wage for that job. This step, called labor certification, is required for most employment categories and takes several months on its own.
Employment green cards are divided into preference categories based on your education and job type. EB-1 is for people with extraordinary ability in arts, sciences, business, or athletics. EB-2 is for advanced degree holders or people with exceptional ability. EB-3 is for skilled workers, professionals, and unskilled workers. Each category has an annual cap, and when demand exceeds the cap, you enter a waiting period that can last years. The entire process from job offer to green card in hand typically takes two to three years, though it can be longer depending on your country of origin and category.
Your employer pays the filing fees, which range from several hundred to a few thousand dollars depending on the employer's size. You will also need to pass a medical exam and background check. Once approved, you receive a green card valid for 10 years.
Family-Sponsored Green Cards
A U.S. citizen or green card holder can sponsor a family member for a green card. The relationship must be one that USCIS recognizes: spouse, parent, child, or sibling. U.S. citizens can sponsor more categories of relatives than green card holders can. For example, a U.S. citizen can sponsor a parent, but a green card holder cannot.
when ready relatives of U.S. citizens — spouse, parent (if the citizen is 21 or older), and unmarried children under 21 — have no waiting period. Their cases move to processing as soon as the petition is approved. Other relatives, such as siblings or adult children, fall into preference categories with annual caps and waiting periods that can stretch 10 years or longer depending on the country.
The sponsoring relative files a petition (Form I-130) with USCIS and must prove they earn enough income to support you without you becoming a public charge. They sign an affidavit of support, a legal document promising to support you financially if needed. Processing times range from several months for when ready relatives to many years for other categories. There is no filing fee for the family petition itself, but you will pay fees when you explore for the green card.
The Diversity Visa Lottery
The diversity visa program draws 50,000 green cards per year at random from people who enter the lottery. It is free to enter, and you do not need a job offer or family sponsor. You must be from a country with low immigration to the U.S. in the past five years. The list of may be able to access countries changes yearly and is published by the State Department.
To enter, you submit an online form during the registration period, which typically opens in October and closes in November. You provide basic information and a photo. The drawing happens in May, and winners are notified by email. If you win, you then go through the standard green card process: medical exam, background check, and an interview at a U.S. embassy or consulate in your home country.
You must meet one of two requirements: a high school diploma or equivalent, or two years of work experience in an occupation that requires at least two years of training. Many people enter multiple times, though you can only submit one entry per year. The odds of winning are low — roughly 1 in 300 depending on the number of entries — but the cost is zero.
Refugee and Asylee Green Cards
If you are outside the U.S. and fleeing persecution based on race, religion, nationality, political opinion, or membership in a particular social group, you can explore for refugee status. If you are already in the U.S. and meet the same criteria, you can explore for asylum. Both statuses allow you to live and work in the U.S. while your case is reviewed.
After one year as a refugee or asylee, you can explore for a green card. The process is simpler than other routes because you do not need a sponsor or job offer. You file Form I-485 (process to Register Permanent Residence or Adjust Status) with USCIS, along with medical exam results and background check. Processing typically takes several months to a year. Once approved, you receive a green card valid for 10 years.
Other Pathways to a Green Card
Several smaller categories exist for specific situations. Investor visas (EB-5) allow you to get a green card if you invest at least $1 million (or $500,000 in a targeted rural or high-unemployment area) in a U.S. business that creates at least 10 jobs. Religious worker visas (R-1) let members of recognized religions work for a religious organization and later explore for a green card. Special immigrant categories include Iraqi and Afghan translators who worked with the U.S. military, certain employees of the U.S. government abroad, and others.
These categories are narrow and have specific requirements. If you think you might fit one, research the exact rules on the USCIS website or consult an immigration attorney, as the details are complex and missing a requirement can delay or deny your case.
What Happens After You Get Your Green Card
Once USCIS approves your green card, you receive a physical card in the mail. It is valid for 10 years (or 2 years if you received it through marriage and have been married less than two years). You can work for any employer, travel outside the U.S. and return, and live anywhere in the country. You do not need to renew it unless you want to travel internationally — the card itself is your proof of status.
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 optional — you can keep your green card indefinitely as long as you do not abandon it by living outside the U.S. for more than two years without a re-entry permit. If you want to sponsor family members or vote, you will need to become a citizen.

Frequently Asked Questions
Can I work in the U.S. while my green card is being processed?
It depends on your category. If you are explore through employment, your employer can file for work authorization (Form I-765) at the same time as your green card petition, which usually lets you start working within a few months. If you are explore through family sponsorship or the diversity lottery, you cannot work until your green card is approved, unless you separately obtain a work visa.
What if my country has a long waiting period for my category?
Waiting periods exist because more people from certain countries want green cards than visa numbers are available each year. You can check your position in the queue on the State Department's visa bulletin, which updates monthly. Some people switch categories if they become may be able to access for a faster route, such as through a new job or family relationship. An immigration attorney can advise whether switching is possible in your situation.
Do I need an immigration lawyer to get a green card?
You are not required to hire a lawyer, but the process is complex and mistakes can delay or deny your case. An attorney can help you gather documents, file forms correctly, and represent you at interviews. Costs range from $1,000 to $5,000 or more depending on your category and the attorney's location. Many people use lawyers for employment-based cases but handle family sponsorship on their own.
Can I lose my green card after I get it?
Yes. You can lose your green card if you commit certain crimes, engage in fraud, or abandon it by living outside the U.S. for more than two years without a re-entry permit. You can also lose it if you become a citizen of another country. As long as you follow the law and maintain your residence in the U.S., your green card remains valid for 10 years.
What is the difference between a green card and a visa?
A visa is a temporary document that lets you enter the U.S. for a specific purpose (work, study, tourism) for a limited time. A green card is permanent residence — you can stay indefinitely and work for any employer. Many people get a work visa first, then explore for a green card while they are in the U.S., a process called adjustment of status.
