Immigration status types in the U.S.: A complete guide

What is the difference between a Visa and an immigration status?

A visa is a travel document placed in your passport by a U.S. consulate or embassy. It allows you to travel to a U.S. port of entry and request admission. It does not guarantee entry, nor does it control how long you can stay.

Your immigration status is what you are granted upon admission to the United States. It is typically documented on your Form I-94 and determines how long you can remain in the country and what activities you are allowed to do.

For example, your visa could expire while you are still in a valid status, and that is generally allowed. What matters is the end date on your I-94 or the conditions tied to your status, not the visa stamp itself.

U.S. citizen

U.S. citizenship is the most complete immigration status. It provides the highest level of rights and protection under U.S. law.

There are three main ways to become a U.S. citizen. You can be born in the United States under the principle of birthright citizenship. You can acquire citizenship through a U.S. citizen parent, depending on specific legal requirements. Or you can apply for naturalization after holding a green card for the required period, usually 5 years, or 3 years if married to a U.S. citizen.

Citizens have the right to vote, apply for federal jobs, hold a U.S. passport, and sponsor a wider range of family members for immigration. Citizenship is generally permanent and can be revoked only in limited circumstances, such as fraud during the naturalization process.

Lawful permanent resident (Green card holder)

A lawful permanent resident, often called a green card holder, has permission to live and work in the United States indefinitely.

Green cards are issued as Form I-551 and can be obtained through several pathways. These include family sponsorship, employment-based petitions, asylum or refugee status, and the diversity visa lottery.

As a green card holder, you can live and work anywhere in the U.S., travel internationally, and petition for certain family members. However, there are limits. You cannot vote in federal elections, and extended time outside the U.S. or certain criminal issues can put your status at risk.

Nonimmigrant Visa holders (Temporary status)

Nonimmigrant status covers people who are in the United States temporarily for a specific purpose. There are many different visa categories, each with its own rules and time limits.

Tourist and visitor visas (B-1/B-2)

B-1 and B-2 visas are among the most common. They allow short-term visits for business or tourism, usually for up to six months at a time. Employment is not permitted under these visas.

Some travelers enter the United States through the Visa Waiver Program using ESTA, which allows stays of up to 90 days without a visa for eligible countries.

Student visas (F-1 and M-1)

F-1 visas are for academic students enrolled in approved institutions. These are typically issued for “duration of status,” meaning you can stay as long as you remain a full-time student and follow program rules.

Students may qualify for temporary work opportunities such as Optional Practical Training, including STEM extensions in certain fields. M-1 visas are for vocational or non-academic programs.

Work visas

Work visas allow you to be employed in the United States under specific conditions.

Common examples include H-1B visas for specialty occupations, L-1 visas for intracompany transfers, O-1 visas for individuals with extraordinary ability, TN visas for Canadian and Mexican professionals, and E-3 visas for Australian nationals.

Most of these visas are tied to a specific employer, meaning a job change usually requires a new petition. If you’re exploring work visa options, Marble’s immigration team can help you understand which pathways may apply to your situation.

Family and fiancé visas

Family-based temporary visas include the K-1 fiancé visa, which allows you to enter the U.S. to marry a U.S. citizen within 90 days. After marriage, you can apply for a green card.

There are also less commonly used categories, such as the K-3 for spouses of U.S. citizens and the V visa for certain family members of permanent residents. These cases can be complex, and working with an immigration lawyer can help you avoid delays.

Humanitarian nonimmigrant categories

Some nonimmigrant visas are designed to protect vulnerable individuals.

T visas are for victims of human trafficking, and U visas are for victims of certain crimes who assist law enforcement. Both categories can lead to a green card over time, but they involve detailed eligibility requirements.

Deferred action and DACA

Deferred Action for Childhood Arrivals, or DACA, is not a formal immigration status. It is a policy that allows certain individuals who were brought to the U.S. as children to remain temporarily without being removed.

To qualify, applicants must meet specific criteria, including continuous residence in the U.S. and certain education or military requirements. DACA protects recipients from removal for renewable two-year periods and allows recipients to apply for work authorization.

However, it does not provide a lawful status or a direct path to a green card under current law.

Asylum seekers and asylees

Asylum is a form of protection for individuals who fear persecution in their home country based on factors like race, religion, nationality, political opinion, or membership in a particular social group.

An asylum seeker is someone who has applied for protection and is waiting for a decision. An asylee is someone whose application has been approved.

Applications can be filed affirmatively with USCIS or defensively in immigration court. In most cases, asylum must be requested within one year of entering the United States, although there are exceptions.

If granted asylum, you can eventually apply for a green card and later citizenship.

Refugees

Refugees are similar to asylees in terms of eligibility, but the process happens outside the United States.

Refugees are screened and approved for admission to the U.S. through the U.S. Refugee Admissions Program, often with referrals from international organizations. Once admitted, they are authorized to work immediately and must apply for a green card after one year.

Parole and temporary protected status (Tps)

Some humanitarian protections do not fall neatly into traditional immigration status categories.

Humanitarian parole

Humanitarian parole allows individuals to enter the United States temporarily for urgent reasons or significant public benefit. It does not grant formal immigration status or a direct path to permanent residency.

However, parolees may still be eligible to apply for other forms of relief while in the U.S.

Temporary protected status (Tps)

TPS is granted to nationals of certain countries facing armed conflict, natural disasters, or other extraordinary conditions.

It allows individuals to remain in the United States temporarily and obtain work authorization. TPS does not lead directly to a green card, and designations are reviewed and updated by the government.

Undocumented / No immigration status

Some individuals in the United States do not have a current lawful immigration status. This may happen if they entered without inspection, overstayed a visa, or lost a previous status.

Being undocumented means you are subject to removal under U.S. law, but it does not always mean immediate enforcement action. In some cases, there may still be options available, such as asylum, humanitarian visas, or certain family-based pathways.

Each situation is different, and understanding your options requires a careful review of your circumstances.

How immigration status affects key rights and benefits

Your immigration status directly affects what you can and cannot do in the United States.

Some statuses allow unrestricted work authorization, while others limit or prohibit employment. Travel rights also vary, with some categories allowing easy re-entry and others carrying a significant risk if you leave.

Eligibility to sponsor family members, access certain public benefits, and even exposure to deportation all depend on your status. These differences can have a major impact on long-term planning.

How can immigration status change?

For many people, immigration status is not permanent and can change over time.

You may be able to extend your current status by applying before your authorized stay ends. In some cases, you can change from one non-immigrant category to another while remaining in the U.S.

If you qualify through family or employment, you may be able to apply for a green card through adjustment of status or consular processing. After holding a green card for the required period, you may be eligible to apply for citizenship.

Each pathway has its own requirements and risks, especially if prior immigration violations are involved.

Final Thoughts

Immigration status types in the U.S. are not just labels. They determine your rights, your risks, and your future options.

Because the system is complex, it’s easy to misunderstand where you stand or what your next steps should be. Taking the time to understand your current status is one of the most important things you can do.
