The Four Immigration Statuses in the U.S., Explained

Published 15 October 2026

“What is your status?” is the first question any immigration lawyer asks, because almost every other answer depends on it. The law recognizes dozens of specific categories, but they group into four tiers, from the most secure to the least. This guide explains each tier, the gray zone between them, and how people move from one to another.

The four tiers at a glance

1. U.S. citizens

Citizenship is the only status that cannot be taken away for living abroad or for a criminal conviction. There are three ways to have it:

• Birth in the United States. Under the Fourteenth Amendment, almost everyone born on U.S. soil is a citizen, whatever their parents’ status. The Supreme Court reaffirmed this on 30 June 2026 in Trump v. Barbara (see “Where things stand” below).
• Through parents. A child born abroad to a U.S. citizen parent may be a citizen at birth if the parent meets residence requirements. A child under 18 who lives in the U.S. as a green card holder with a parent who naturalizes usually becomes a citizen automatically.
• Naturalization. Most green card holders can apply on Form N-400 after five years as a permanent resident, or three years if they have been married to and living with a U.S. citizen. The process includes an English and civics test. USCIS explains the requirements on its citizenship and naturalization page.

Citizens can vote, hold a U.S. passport, petition for parents, siblings and married children, and cannot be deported. Citizenship obtained by naturalization can be revoked only through a court process, mainly for fraud in the application.

2. Lawful permanent residents (green card holders)

A permanent resident may live and work anywhere in the country indefinitely. The card itself expires every ten years and must be renewed; the status does not expire. What permanent residents need to know:

• Conditional residents — people whose green card came through a marriage less than two years old, or through EB-5 investment — get a two-year card and must file to remove the conditions before it expires.
• Long trips abroad are risky. An absence of more than six months invites questions at the border. An absence of a year or more is presumed to be abandonment of residence unless you got a reentry permit before leaving. USCIS covers this on its international travel page.
• A green card can be lost. Certain criminal convictions, immigration fraud and voting in a federal election are grounds for removal.
• Permanent residents aged 18 and over must carry their card, under 8 U.S.C. §1304(e).

The full list of rights and responsibilities is published by USCIS.

3. Temporary (nonimmigrant) status

Nonimmigrants are people allowed in for a specific purpose and a limited time. The categories are named by letter: B for visitors, F and M for students, J for exchange visitors, H-1B for specialty workers, L for intracompany transferees, O for people of extraordinary ability, E for treaty traders and investors, TN for Canadian and Mexican professionals, and others. The State Department lists them in its directory of visa categories.

Three rules catch people out:

• A visa is not a status. The visa in your passport lets you ask to enter. Your status, and how long you may stay, is set by CBP on your I-94 record.
• You must do only what your category allows. A tourist who takes a job, or a student who drops below a full course load, has violated status even if the I-94 has not expired.
• Most categories require intent to return home. Applying for a green card while in a category such as B-2 or F-1 is not forbidden, but the timing can raise fraud questions. A few categories, such as H-1B and L-1, allow “dual intent.”

Status can often be extended or changed inside the U.S. by filing with USCIS before it expires.

4. No lawful status

People without lawful status are in one of two situations: they entered without inspection (crossed the border without being admitted), or they entered lawfully but overstayed or violated their status. The difference matters a great deal later, because the main way to get a green card inside the U.S. generally requires that you were inspected and admitted or paroled.

The key consequences:

• Unlawful presence accumulates. More than 180 days followed by departure triggers a 3-year bar on returning; a year or more triggers a 10-year bar. Re-entering or trying to re-enter illegally after a year of unlawful presence can trigger a permanent bar. These rules are in INA §212(a)(9). Some spouses and children of U.S. citizens can ask for a waiver before leaving using the provisional waiver, Form I-601A.
• A visa overstay cancels the visa. Even a multi-year visa is void after an overstay, and a new one usually must be applied for in your home country.
• Registration is now enforced. Noncitizens 14 and older who have never been registered — mostly people who entered without inspection and never applied for anything — must register with USCIS. The government began enforcing this in 2025 with Form G-325R; see USCIS’s Form G-325R page. Registering does not give status or work authorization.
• Constitutional protections still apply. People without status still have due-process rights, and most are entitled to a hearing before an immigration judge before being deported. A major exception is expedited removal.

The gray zone: protected, but not “in status”

Large numbers of people in South Florida are in none of the four tiers cleanly. These categories protect against removal or allow work, but most do not lead to a green card by themselves:

• Asylees and refugees are the exception: they have lawful status and can apply for a green card after one year.
• Temporary Protected Status (TPS) protects nationals of designated countries from removal and allows work while the designation lasts. When a designation ends, holders return to whatever status they had before.
• Parole lets someone into the country without a formal admission, for humanitarian or public-benefit reasons. It is temporary. But the green card rules treat a parolee as someone who was inspected, so parole can make adjustment of status possible later through another route, such as marriage to a U.S. citizen.
• DACA and other deferred action are decisions not to deport someone for a period. They do not create status, but unlawful presence does not accrue while they last.
• Pending applicants — for example, people with an asylum application or a green card application on file — may have work permits and protection while the case is pending, but no status until it is approved.

How people move between tiers

A common path upward: a student enters on an F-1, works on OPT, is sponsored for an H-1B, then an employer files for a green card, and five years later the worker naturalizes. A common path downward: a visitor enters on a B-2, stays past the I-94 date and is out of status, then starts building unlawful presence.

Two people who look the same today can have very different options because of how they came in. An overstay married to a U.S. citizen can often adjust status without leaving. Someone who entered without inspection and has the same marriage usually has to process abroad and needs a waiver of the bars. That is why a lawyer will always ask how and when you entered, and what documents you were given.

How to check your own status

• Your I-94, from the CBP I-94 website, shows your class of admission and the date you must leave by.
• Your I-797 approval notices show any extension or change of status USCIS has granted.
• Your green card or work permit shows the category code.
• If you are unsure what is in your file, a FOIA request to USCIS, CBP or EOIR will return your records.
