U.S. Permanent Resident vs. U.S. Citizen: What's the Difference?

Green card holders can in theory stay in the U.S. indefinitely, but it's not as secure a status as U.S. citizenship.

By , J.D.

The terms "permanent resident" and "U.S. citizen" are often confused with one another. Although both confer rights to live legally in the United States, potentially for one's entire life, they mean very different things, as described below.

What U.S. Lawful Permanent Resident Status Means

A lawful permanent resident is someone who has been granted the right to live in the United States for an indefinite time; possibly their entire life. Permanent residents are given what's known as a "green card," which is a photo ID card that proves their status.

A grant of permanent residence includes the right to work in the U.S. and to petition for close family members (spouse and unmarried children) to receive permanent residence and join you. However, your family members will be considered "preference relatives," meaning that only a limited number of immigrant visas are available to such people per year, and a waiting list usually develops (based on "priority date"). Your relatives could spend around five years on a waiting list before being allowed to enter or remain in the United States or get a green card (though wait times have been less in recent years, with no wait at all for spouses and minor children).

Permanent residents remain citizens of another country. So every time you travel outside the United States, you must carry the passport of that country with you, as well as your U.S. green card. You will use your green card to reenter the United States.

There are important limitations on lawful permanent residents' rights. You do not have any rights to vote in U.S. elections, and can be prosecuted and lose your chance at U.S. citizenship if you do so.

If you leave the United States with the intention of making your home elsewhere, you will be considered to have abandoned your residence and given up your green card. Contrary to popular myth, you can abandon your residence in as little as one day, based on your intentions upon departure. However, it's true that immigration authorities will take an especially close look if you spend more than six months outside the United States.

And if you spend more than a year outside the United States, the authorities will definitely presume that you have abandoned your residence. You will have an uphill battle convincing them otherwise. If you plan to leave the U.S. for a period exceeding 12 months, it's a good idea to obtain a reentry permit first.

Upon return from foreign travel, you will be subject to the same grounds of inadmissibility as you faced when you first got the green card. So, for instance, if you have been receiving financial-need based government assistance or welfare, you could be excluded at the border as a likely public charge.

Another important limitation on lawful permanent residents is that they are subject to the grounds of deportability. If you commit certain crimes or security violations, or even fail to advise USCIS of your changes of address, you can be placed in removal proceedings and deported from the United States.

After a certain length of time (five years in most cases) permanent residents who have shown good moral character and can speak, read, and write English and pass an exam on U.S. history and government can apply for U.S. citizenship (to naturalize).

What U.S. Citizenship Means

Citizenship is the highest immigration status available in the United States and offers many benefits.

People can become U.S. citizens by either:

  • birth in the United States
  • through U.S. citizen parents (depending on the laws in effect at the time of their birth), or
  • through a process known as naturalization.

A U.S. citizen is eligible to receive a U.S. passport, which is issued by the U.S. State department. Many countries allow visa-free travel for U.S. citizens. A U.S. citizen can leave and reenter the U.S. at any time without being subject to the grounds of inadmissibility or requiring a reentry permit. There are no restrictions on the number of days a citizen can remain outside the United States.

U.S. citizens can vote in U.S. federal and local elections, hold certain government jobs, and serve on juries. Many federal and state government grants, scholarships, and other benefits are available only to U.S. citizens.

As a U.S. citizen, you can petition for a number of your relatives to immigrate. Your spouse, unmarried children under age 21, and parents will be considered immediate relatives, and will be eligible to immigrate just as soon as you can get through all the paperwork and interviews. Your married children and children over age 21, as well as your brothers and sisters, are considered preference relatives, and can be put on a waiting list to immigrate. (This can take several years, however, especially for the siblings.)

U.S. citizens cannot be deported from the United States; unless, that is, they committed fraud in order to obtain their green card or citizenship.
