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. It is not citizenship — you remain a citizen of your home country — but it gives you the legal right to stay indefinitely, travel in and out, and hold most jobs without sponsorship.

There are several distinct paths to a green card, and which one applies to you depends on your situation. The main routes are employment-based sponsorship (your employer petitions for you), family sponsorship (a relative petitions for you), diversity visa lottery, refugee or asylee status, and special categories like investment or religious worker visas. Each has different requirements, timelines, and costs.

The process always involves the U.S. Citizenship and Immigration Services (USCIS), and most routes require a petition filed on your behalf before you can move forward. You cannot straightforward explore for a green card on your own — someone (an employer, family member, or in some cases the government through lottery) must sponsor you or you must fall into a category like refugee status.

Key Takeaways

  • A green card requires sponsorship through employment, family, diversity lottery, refugee status, or other special categories — you cannot explore without a sponsor in most cases.
  • The process begins with a petition filed by your sponsor (Form I-140 for employment, Form I-130 for family), not by you directly.
  • After the petition is approved, you must show you have a job offer (employment cases), sufficient family support (family cases), or meet other category requirements, plus pass medical and background checks.
  • Processing times vary widely by category and country of origin, ranging from months to many years, and visa availability is limited each year.
  • Costs include filing fees (currently around $640 for the green card process itself), medical exams, and often immigration attorney fees if you hire one.

Employment-Based Green Cards: Sponsorship by Your Employer

If your employer wants to sponsor you, they file Form I-140 (Immigrant Petition for Alien Worker) with USCIS on your behalf. This petition must show that the job requires your specific skills and that the employer has tried to recruit U.S. workers first. Most employment-based green cards fall into one of five preference categories, ranked by skill level and labor market need.

Before your employer can file the I-140, they typically must obtain a labor certification from the Department of Labor. This document proves that hiring you will not displace U.S. workers and that wages in your area support the salary being offered. The labor certification process can take one to three years on its own. Some jobs (certain professionals, executives, and workers with advanced degrees) may skip this step under the EB-1 or EB-2 categories.

Once the I-140 is approved, you move into the visa availability queue. The State Department publishes a Visa Bulletin each month showing which preference categories have current visa numbers available. If your category is current, you can proceed to the next step. If not, you wait — sometimes for years — until your priority date (the date your labor certification was filed) becomes current.

When a visa number is available, you file Form I-485 (process to Register Permanent Residence or Adjust Status) if you are already in the United States, or you go through consular processing if you are abroad. Either way, you must pass a medical exam, background check, and interview.

Family-Based Green Cards: Sponsorship by a Relative

A U.S. citizen or green card holder can sponsor certain relatives. U.S. citizens can sponsor spouses, parents, and siblings without numerical limits, but green card holders can only sponsor spouses and unmarried children. The closer the relationship, the faster the process typically moves.

Your sponsor files Form I-130 (Petition for Alien Relative) with USCIS. If your sponsor is a U.S. citizen and you are their spouse, parent, or child under 21, your petition may be processed quickly — sometimes within months. If you are a sibling or adult child, or if your sponsor is a green card holder, you enter a preference category with annual numerical limits, and wait times can stretch to many years.

Your sponsor must also show they have enough income to support you. They file Form I-864 (Affidavit of Support), proving their household income is at least 125 percent of the federal poverty line (or 100 percent if they are a military member). If their income is too low, they can add a joint sponsor — another person who agrees to support you financially.

Once the I-130 is approved and a visa number is available (or when ready, if you are in an unlimited category), you file I-485 or go through consular processing, just as in employment cases. You must pass medical and background checks and attend an interview.

Diversity Visa Lottery and Other Routes

The Diversity Visa Program randomly selects 50,000 people per year from countries with low immigration to the United States. If your country is may be able to access and you meet basic education or work experience requirements, you can enter the lottery for free during the annual registration period (usually October through November). Winners are selected by random drawing, and if you win, you can proceed to the green card process process.

Other routes exist for specific situations. Refugees and asylees can explore for a green card after one year of status in the United States. Special immigrant categories include religious workers, Iraqi and Afghan translators, and certain other groups. Investment-based green cards (EB-5) require you to invest a minimum amount of money in a U.S. business that creates jobs.

If you have been a victim of human trafficking, domestic violence, or certain crimes, you may be may be able to access for a T visa or U visa, which can lead to a green card after three years. These routes are narrower and have specific may be able to access rules, but they do not require a sponsor in the traditional sense.

The Medical Exam, Background Check, and Interview

Once your petition is approved and a visa is available, you must pass a medical exam performed by a USCIS-designated civil surgeon or panel physician. The exam checks for communicable diseases and certain health conditions. You will receive vaccinations if you are not up to date, and the cost (typically $200 to $500) is your responsibility. Some conditions may require a waiver, which adds time and cost.

USCIS will conduct a background check that includes fingerprinting, name checks, and security clearances. This process can take weeks to months. If you have a criminal record, immigration violations, or security concerns, your case may be delayed or denied.

You will attend an interview with a USCIS officer (if adjusting status in the U.S.) or a consular officer (if processing abroad). The officer will review your process, ask about your background, verify your documents, and confirm that you meet all requirements. Most interviews last 15 to 30 minutes, though complex cases may take longer. Bring original documents, not copies: your passport, birth certificate, marriage certificate (if applicable), police clearance, medical exam results, and any other documents requested in your notice.

Processing Times and Visa Availability

How long the entire process takes depends heavily on your category and country of origin. when ready relatives of U.S. citizens (spouses, parents, children under 21) may see their green card in 6 to 12 months. Employment-based categories can take 2 to 10 years or longer, especially if your country has a backlog — nationals of India and China, for example, often wait many years because demand exceeds the annual visa limit.

The State Department publishes the Visa Bulletin monthly, which shows the current priority date for each category. You can check this bulletin to see whether your category is current or how far behind you are. Some months a category moves forward; other months it may move backward if demand is high.

Processing times also vary by USCIS office. Some offices handle cases faster than others. You can check the USCIS website for processing times at your local office, though these are estimates and actual times may differ.

Costs and What to Expect to Pay

The filing fees for a green card process (Form I-485) are currently around $640, plus a biometric services fee of about $85. If you are adjusting status in the United States, you may also need to pay for a medical exam ($200 to $500), police clearance documents (varies by country), and translation services if your documents are not in English.

If you hire an immigration attorney — which is not required but is common — expect to pay $1,500 to $5,000 or more depending on the complexity of your case and your location. Some attorneys charge flat fees; others charge hourly rates.

Employment-based cases may also require a labor certification, which involves Department of Labor fees and advertising costs paid by your employer, typically totaling $500 to $2,000. Your employer may cover these costs or pass them to you — this varies by company and agreement.

If you are processing abroad through consular processing, you will also pay a visa processing fee (around $325) and may need to pay for travel to the U.S. consulate in your country.

Common Mistakes and What to Avoid

One of the most common mistakes is not understanding that you cannot explore for a green card on your own. You must have a sponsor or fall into a category like refugee status. If you are waiting for a family member or employer to petition for you, do not overstay a visa or work without authorization in the meantime — this can make you ineligible or cause serious delays.

Another mistake is providing incomplete or inaccurate information on your process. USCIS cross-checks your statements against government records, and discrepancies can lead to denial or fraud findings. If you have made a mistake on a previous process, disclose it and explain it clearly rather than hoping it goes unnoticed.

Do not assume your case is moving forward without checking. After you file, you can check the status online using your receipt number. If you do not receive a decision within the estimated timeframe, contact USCIS or your attorney to find out what is happening.

If you are in the United States on a visa, understand the rules for your visa type. Some visas allow you to file for a green card while maintaining status; others do not. Filing for a green card while on certain visas can be seen as abandoning your visa intent, which may cause problems. An immigration attorney can advise you on whether it is safe to file in your situation.

Frequently Asked Questions

How long does it take to get a green card?

It depends on your category. when ready relatives of U.S. citizens typically wait 6 to 12 months. Employment-based cases often take 2 to 10 years or longer, especially for nationals of countries with high demand. Family preference categories and diversity visa winners usually wait 1 to 5 years. Check the State Department Visa Bulletin for your specific category and country.

Can I work while my green card process is pending?

If you are in the United States and have filed Form I-485, you can request work authorization (Form I-765) at the same time. Once approved, you can work for any employer. If you have not filed I-485 yet, you can only work if your visa allows it or if your employer has filed for work authorization separately. Do not work without authorization — it can disqualify you.

What happens if my green card process is denied?

You will receive a notice explaining the reason for denial. You may be able to appeal or reapply if the issue can be fixed. Some denials are final, such as those based on criminal history or fraud. An immigration attorney can review your denial notice and advise whether an appeal is possible in your case.

Do I need an attorney to get a green card?

An attorney is not required, but many people hire one because the process is complex and mistakes can be costly. If your case is straightforward (when ready relative of a U.S. citizen, for example), you may be able to handle it yourself. If your case involves employment, a backlog, or any complications, an attorney can significantly improve your chances and reduce stress.

Can I travel outside the United States while my green card process is pending?

If you are adjusting status in the United States, traveling abroad before your green card is approved can be risky — you may not be allowed back in. If you must travel, request advance parole (Form I-131) before you leave. If you are processing through a U.S. consulate abroad, you must remain outside the United States until your visa interview and approval.
