A green card and an immigrant visa are two different documents that work together
An immigrant visa is the document you receive from a U.S. consulate abroad that allows you to enter the United States and become a permanent resident. A green card (officially called a Permanent Resident Card) is the physical ID card you receive after you arrive in the U.S. and go through customs. You cannot have a green card without first obtaining an immigrant visa—the visa is the entry ticket, and the green card is what you carry once you are here.
Think of it this way: the immigrant visa gets you through the door. The green card proves you belong on the other side of it. You will use the immigrant visa only once, to board your flight and pass through U.S. immigration at the airport or border. After that, you will use your green card for everything else—working, traveling, proving your legal status, and eventually explore for citizenship if you choose to.
Key Takeaways
- An immigrant visa is issued by a U.S. consulate outside the United States and allows you to enter the country as a permanent resident.
- A green card is the physical ID card you receive after arriving in the U.S., and it proves your permanent resident status.
- You must obtain an immigrant visa before you can receive a green card—the visa is the first step, the card is the second.
- The immigrant visa is used only once to enter the country; the green card is your ongoing proof of legal permanent residence.
- Both documents grant you the same legal status: permanent resident of the United States.
The order of events: visa first, then green card
The process starts with an immigrant visa. You or a family member or employer must petition for you through the U.S. immigration system. Once your petition is approved and your visa category has an available slot, you will go to a U.S. consulate in your home country (or another country where you are legally present) for an interview. At that interview, a consular officer will review your documents, ask you questions, and decide whether to issue you an immigrant visa.
If the consulate approves you, they will stamp your passport with the immigrant visa. This visa is valid for a limited time—usually six months—and it is your permission to travel to the United States. When you arrive at a U.S. airport or land border, a customs and border protection officer will inspect your documents, admit you to the country, and record your arrival. Within weeks, you will receive your green card by mail at the address you provided.
From that point forward, the green card is your primary document. You will carry it when you travel, show it to employers, and present it to government agencies. The immigrant visa in your passport becomes a historical record—you keep it, but you do not use it again.
What each document lets you do
An immigrant visa serves one purpose: it authorizes you to board a plane or cross a border and enter the United States as a permanent resident. You cannot work, travel, or live in the U.S. on an immigrant visa alone. The visa is only valid for entry. Once you use it to enter the country, it has done its job.
A green card gives you much broader rights. With a green card, you can live and work anywhere in the United States without needing a separate work permit. You can travel outside the U.S. and return (as long as you do not stay away for more than one year without filing a re-entry permit). You can sponsor family members for their own green cards. You can own property, start a business, and attend school. You are also required to pay U.S. income taxes on your worldwide income, just as U.S. citizens do.
Both documents grant you the same underlying status: permanent resident. The difference is that the visa is your entry document, and the card is your proof of that status once you are here.
Why you need both documents, not just one
The U.S. immigration system requires both documents because they serve different functions at different times. The immigrant visa is issued by the State Department overseas and proves that a consular officer has reviewed your background and found you admissible. It is the official permission to enter.
The green card is issued by U.S. Citizenship and Immigration Services (USCIS) after you arrive and is your proof of permanent resident status while you live in the country. It is tied to your fingerprints and photograph, making it harder to forge or transfer. Requiring both documents creates a checkpoint at entry and a clear record of who is in the country legally.
You cannot skip the immigrant visa and go straight to a green card. The visa is the legal pathway into the system. Without it, you cannot enter the country, and without entering, you cannot receive a green card.
How long each document lasts
An immigrant visa is valid for a limited time, usually six months from the date it is issued. You must use it to enter the United States within that window. If you do not travel within six months, the visa expires and you will need to request a new one from the consulate. This rarely happens because most people travel as soon as their visa is ready, but it is important to know the important date.
A green card is valid for ten years from the date it is issued (or two years if you are a conditional permanent resident, which applies to some spouses and investors). You can renew it before it expires by filing a form with USCIS. As long as you maintain your permanent resident status—meaning you do not commit certain crimes, do not abandon your residence in the U.S., and do not take actions that show you intend to give up your status—you can keep renewing your green card indefinitely.
What happens if you lose your immigrant visa or green card
If you lose your immigrant visa before you travel, you will need to request a replacement from the consulate. This is usually a straightforward process, but it takes time. If you have already used your visa to enter the country, losing the visa stamp in your passport is not a problem—you have already accomplished what it was for. Keep your passport safe, but the visa itself is no longer critical once you are in the U.S.
If you lose your green card, you must report it to USCIS and request a replacement. You can file the replacement request by mail or online, and USCIS will issue a new card. Until the new card arrives, you can request a travel document or an employment authorization document if you need to prove your status. Losing your green card is inconvenient but not a loss of your permanent resident status—the status exists in the government's records regardless of whether you have the physical card.
Common confusion: green card holders and visa holders
People sometimes use the term "visa holder" to mean anyone who is not a U.S. citizen, but that is not accurate. A green card holder is not a visa holder—a green card holder is a permanent resident. Visa holders are people on temporary visas, such as student visas, work visas, or tourist visas. These are completely different categories with different rights and restrictions.
If you have a green card, you are not on a visa. You have already passed through the visa stage and moved into permanent resident status. This is an important distinction because employers, schools, and government agencies treat permanent residents and visa holders very differently. Make sure anyone reviewing your status understands that you hold a green card, not a temporary visa.
Frequently Asked Questions
Can I travel outside the U.S. on my immigrant visa?
No. Your immigrant visa is only for entering the United States. Once you are in the country, you use your green card to travel. If you leave the U.S. and want to return, you will need your green card to re-enter—the immigrant visa cannot be used a second time.
What if my immigrant visa expires before I can travel to the U.S.?
You will need to request a new visa from the consulate. Contact the consulate where you applied and explain that your visa expired before you could use it. They can issue a replacement, though the process takes several weeks. Make sure you travel within the new visa's validity period.
Do I need to carry my immigrant visa with me after I get my green card?
No. Once you have your green card, you only need to carry the green card. Your immigrant visa stays in your passport as a record, but you do not need to show it to anyone. The green card is your proof of status.
Can I work in the U.S. on an immigrant visa before my green card arrives?
Yes, but only after you have entered the country. The immigrant visa itself does not authorize work, but once you arrive and are admitted as a permanent resident, you can work when ready while you wait for your physical green card to arrive by mail. You do not need a separate work permit.
What is the difference between an immigrant visa and a non-immigrant visa?
An immigrant visa is for people who intend to live permanently in the United States. A non-immigrant visa is for people who intend to stay temporarily, such as for school, work, tourism, or medical treatment. Non-immigrant visas have expiration dates and do not lead to permanent resident status unless you change your status through a separate process.
