Key Facts

Federal level: A green card is Form I-551, the federal document that shows its holder has lawful permanent resident status in the United States.
Federal level: Permanent residence is an immigration status; the physical card is evidence of that status, so an expired card does not by itself mean the status expired.
Federal level: Lawful permanent residents generally may live and work permanently in the United States, but the status can be lost through abandonment or a final removal order.
Federal level: Some marriage-based residents receive conditional permanent residence for two years and must use the applicable process to remove those conditions.

“Green card” is the familiar name for the Permanent Resident Card, Form I-551. The card proves that its holder is a lawful permanent resident, often shortened to LPR. Federal law defines lawful permanent residence as the status of having been lawfully granted the privilege of residing permanently in the United States as an immigrant while that status has not changed.

That distinction between the card and the status matters. A plastic card can expire, be lost, or need replacement while the underlying immigration status continues. Conditional residence is different: in those cases, the status itself is time-limited unless the conditions are properly removed.

What a green card allows

Lawful permanent residents generally may live permanently in the United States, work in lawful employment for which they qualify, and receive the protection of federal, state, and local law. They may also travel outside the country and seek to return, subject to federal immigration rules at the border.

Permanent residence is not U.S. citizenship. Green card holders cannot vote in federal elections, and some jobs are limited to U.S. citizens for legal or security reasons. Many LPRs can later pursue U.S. citizenship through naturalization, but naturalization is a separate application with its own eligibility requirements.

Federal responsibilities accompany the status. These include obeying federal, state, and local laws and filing required income tax returns as a resident. Federal law also requires a registered noncitizen age 18 or older to carry the registration document issued to that person.

How someone becomes a permanent resident

There is no single green card application route for everyone. Federal immigration law provides multiple eligibility categories, including family relationships, employment, humanitarian programs, the diversity visa program, and certain special immigrant classifications. Each category has distinct requirements, numerical limits, waiting rules, and grounds of inadmissibility.

The process also depends on where the person is applying. A person already in the United States who qualifies may seek adjustment of status, usually through Form I-485. A person abroad commonly completes immigrant-visa processing through the Department of State and becomes a permanent resident upon admission to the United States on that immigrant visa.

An approved immigrant petition does not always produce a green card immediately. In preference categories subject to annual numerical limits, an immigrant visa must be available before the final permanent-residence step can be completed. This is why two cases in the same broad family- or employment-based system can move on very different timelines.

For a broader explanation of the governing system, see this overview of federal immigration law. A separate article on the permanent-residency application process addresses the procedural routes in more detail.

Ten-year cards and two-year conditional cards are not the same

Most permanent resident cards are issued with a ten-year validity period, although the holder’s LPR status ordinarily does not end merely because that card expires. Form I-90 is generally used to replace an expired, expiring, lost, stolen, damaged, or incorrect card.

Marriage-based conditional permanent residents generally receive cards valid for two years. That conditional residence applies when the qualifying marriage was less than two years old when permanent residence was granted. A marriage-based conditional resident generally uses Form I-751 to seek removal of conditions.

A conditional card cannot simply be renewed through the ordinary ten-year-card process. Failure to remove conditions through the applicable federal procedure can result in termination of conditional status. The distinction is explained further in this article about green card renewal.

Travel can affect permanent resident status

A green card supports return from a temporary trip abroad, but it is not an unlimited guarantee of readmission. Federal officials may consider the length and purpose of an absence, the person’s continuing ties to the United States, and whether the person intended the United States to remain a permanent home.

No simple once-a-year visit automatically preserves LPR status. Even an absence shorter than one year can support an abandonment finding when the surrounding facts show that the United States was no longer the person’s permanent home. A prolonged absence can also disrupt the separate continuous-residence requirement for naturalization even when LPR status itself has not been abandoned.

A reentry permit may help document that a longer trip was intended to be temporary, but it does not guarantee admission and does not make abandonment impossible. Voluntary abandonment can be recorded on Form I-407, after which the person is no longer an LPR.

An expired card, expired status, and removal are different events

These terms are easy to blur, but they answer different questions. Card expiration concerns the validity of the document. Abandonment concerns whether the resident intended to keep the United States as a permanent home. Removal concerns a formal immigration process that can end a person’s right to remain.

An LPR may be placed in removal proceedings based on grounds established by federal immigration law. Possessing a green card does not prevent the government from bringing such a case, and only the legally prescribed process determines whether status is lost on that basis.

Green card questions often turn on the category and the record

The words printed on the card are only part of the picture. The immigrant category, “resident since” date, expiration date, travel history, court record, and notices from USCIS can each answer a different legal question. For example, the category may show whether conditions apply, while the resident-since date can matter to later naturalization timing.

A green card therefore functions as evidence of a federal legal status, not as a complete summary of every rule attached to that status. Understanding the difference between document validity, immigration status, travel history, and eligibility category makes the rest of the permanent-residence system much easier to follow.
