- A green card is permanent but conditional. USCIS describes lawful permanent residence as a privilege the government can take away, not an absolute right. Citizenship, once granted, can be lost only in rare court proceedings.
- The permanence of status is the biggest difference. Permanent residents can be placed in removal proceedings for certain crimes or for abandoning their status. Naturalized citizens cannot be deported.
- Only citizens vote, carry a US passport, and hold citizen-only federal jobs. Permanent residents cannot vote in federal elections and cannot get a US passport.
- Citizens have broader family sponsorship rights, including immediate relatives with no annual cap, while permanent residents can sponsor only a spouse and unmarried children in capped categories.
- Both are fully work-authorized. Hiring a permanent resident or a citizen requires no sponsorship, which matters for Form I-9 and E-Verify.
- Naturalization is generally available after 5 years as a permanent resident (or 3 years for those married to and living with a US citizen).
A green card and US citizenship both let you build a life in the United States, but they are not the same status. The difference affects work, travel, family sponsorship, and the security of the status itself. For anyone on an employment-based path through a temporary work visa or an employment-based green card, this guide explains what each status provides, what it requires, and how a permanent resident becomes a citizen. It is written for employees and employers, not for attorneys.
Permanent Resident vs US Citizen: The Core Difference
A green card allows a person to live and work in the United States indefinitely, while citizenship confers full membership with rights that no longer depend on maintaining a status. Permanent residence must be maintained. Citizenship does not.
What Is a Lawful Permanent Resident?
A lawful permanent resident, often called a green card holder, is authorized to live and work permanently in the United States. According to USCIS, a permanent resident may live in the country permanently unless they commit an act that makes them removable, may work in nearly any lawful job (except certain positions limited to US citizens for security reasons), and is protected by federal, state, and local law.
The status carries responsibilities. USCIS lists obeying all laws, filing income tax returns and reporting worldwide income, supporting the democratic form of government, and, for men age 18 through 25, registering with the Selective Service. Permanent residents 18 and older are required to carry their green card and to report any change of address to USCIS within 10 days using Form AR-11.
What Is a US Citizen?
US citizenship can be acquired at birth or after birth. For most people on a work-based path, citizenship comes through naturalization, the process by which a permanent resident becomes a citizen after meeting the requirements in the Immigration and Nationality Act. According to USCIS, only citizens can vote in federal elections, serve on a jury, travel with a US passport, sponsor a wider range of relatives, obtain citizenship for children under 18, hold federal jobs that require citizenship, run for federal office, and keep the right to remain in the country permanently.
The Key Differences That Affect Your Life and Career
The Permanence of Your Status
A permanent resident can lose status. USCIS explains that permanent residence ends if an immigration judge enters a final order of removal, with the grounds for removal set out in the Immigration and Nationality Act. The status can also be abandoned, for example by moving abroad to live permanently or by remaining outside the country for an extended period.
A citizen does not face this risk. Once a person naturalizes, the right to remain cannot be taken away. Citizenship can be revoked only through a federal court proceeding, and only on narrow grounds such as obtaining naturalization illegally or by concealing a material fact.
Voting, Juries, and Public Office
Permanent residents cannot vote in federal elections, and registering or voting as a non-citizen can create severe immigration problems. Citizens can vote in federal elections, serve on federal juries, and run for most public offices.
Passports and International Travel
A green card holder travels on a passport from their home country and presents a valid green card to re-enter the United States. USCIS treats an absence of one year or more as a general indicator of abandoned residence, and long absences can also affect the continuous residence required for naturalization. A permanent resident who expects to be abroad for more than a year may obtain a reentry permit by filing Form I-131 before leaving, which is generally valid for two years.
A citizen travels on a US passport, can request assistance from US embassies and consulates abroad, and faces no abandonment risk regardless of time spent outside the country.
Sponsoring Family Members
Citizens can petition for immediate relatives, which USCIS defines as a spouse, unmarried children under 21, and parents (if the citizen is at least 21). These categories have no annual cap and no waiting list for a visa to become available. Citizens can also petition for married children and for siblings.
Permanent residents have a narrower reach. They can petition only for a spouse and for unmarried children, and those petitions fall in capped preference categories subject to the waits published in the monthly Visa Bulletin. A permanent resident who naturalizes can move a spouse or young child from a capped category into the immediate-relative category, which removes the wait.
Federal Jobs and Security Clearances
Both permanent residents and citizens can work in the private sector without sponsorship. The distinction appears in government work. USCIS notes that some jobs are limited to US citizens for security reasons, and many federal positions and certain security-clearance roles require citizenship.
Taxes and Government Benefits
For tax purposes the two statuses are largely the same: permanent residents and citizens are both taxed on worldwide income. The difference lies in certain public benefits restricted to citizens and in the public charge rules. USCIS confirms that the public charge ground does not apply to naturalization and that renewing a green card does not trigger a public charge review.
Renewal and Maintenance
A standard green card is valid for 10 years and is renewed by filing Form I-90. Conditional residents hold a two-year card and must file to remove the conditions rather than renew. Marriage-based conditional residents file Form I-751 and investor-based conditional residents file Form I-829. Both petitions can be filed 90 days before the expiration of the conditional green card. Citizenship has no expiration and nothing to renew.
How a Green Card Holder Becomes a US Citizen
The path runs through Form N-400.
Naturalization Eligibility (Form N-400)
USCIS sets out the general naturalization requirements. An applicant must be at least 18 and must have been a permanent resident for at least 5 years, or 3 years if married to and living with a US citizen. The applicant must also show continuous residence and physical presence (generally present for at least half the qualifying period), at least 3 months of residence in the state or USCIS district where the application is filed, good moral character, attachment to the Constitution, passing scores on the English and civics tests, and the Oath of Allegiance. An application may be filed up to 90 days before the residence requirement is complete.
For naturalization, USCIS presumes continuous residence is broken by a single absence of more than six months. That presumption can be rebutted with evidence of maintained ties to the United States, while an absence of one year or more generally breaks it.
The 2025 Civics Test Update
The civics test changed in late 2025, and the version an applicant takes depends on the filing date. Applicants who filed Form N-400 before October 20, 2025 take the 2008 test, in which the officer asks up to 10 questions from a bank of 100 and 6 correct answers are needed to pass. Applicants who file on or after October 20, 2025 take the 2025 civics test, in which the officer asks 20 questions from a bank of 128 and 12 correct answers are needed to pass. The English requirement did not change. Applicants who are 65 or older with at least 20 years as a permanent resident continue to take a shorter version, answering 10 questions from a special bank of 20 with 6 correct answers needed to pass.
Fees and Processing Times
The filing fee for Form N-400 is $710 online or $760 by paper, under the USCIS fee schedule effective April 1, 2024. A reduced fee of $380 is available to applicants whose household income is up to 400 percent of the Federal Poverty Guidelines and who file on paper. USCIS reported a national median of about 6.1 months for naturalization in fiscal year 2024 and 5.7 months in fiscal year 2025, and a filing surge in late 2025 raised monthly averages to roughly 7.9 months by early 2026. As of mid-2026, USCIS publishes these figures as uniform national processing times that no longer vary by location, available through the USCIS processing times tool.
For broader context, the Department of Homeland Security reported 818,570 people naturalized in fiscal year 2024, and USCIS naturalization statistics put the median time held as a permanent resident before naturalizing at about 7.5 years.
Why This Difference Matters for Employers and Employees
For Employers
Both permanent residents and citizens are authorized to work without employer sponsorship, and both are acceptable statuses on Form I-9. The green card, not citizenship, is the point at which an employee no longer needs visa support. Citizenship is legally required only for certain roles, such as some federal-contract or clearance positions. The green card stage begins the period that later counts toward naturalization.
For Employees
A federal job, a security clearance, and the freedom to travel and relocate without status concerns are areas where citizenship removes constraints that apply to permanent residents. Maintaining a green card involves carrying it, reporting address changes, renewing on time, and awareness that long absences can affect naturalization eligibility.
The Typical Path
For high-skilled professionals, the path usually runs in three stages. First is a nonimmigrant work visa such as an H-1B, O-1, or L-1. Next is an employment-based green card, through EB-1, EB-2 NIW, or a PERM-based EB-2 or EB-3 with an I-140 petition. Finally, after 5 years as a permanent resident, naturalization becomes available.
How Alma Helps You Reach Permanent Residence
Citizenship is a step a person completes on their own with USCIS after qualifying. Reaching permanent residence is where most employment-based applicants need support, and that is the stage Alma focuses on.
Get Your Employment-Based Green Card Started with Alma
Alma is an attorney-led, technology-enabled platform built for employment-based US immigration, covering temporary work visas and green cards including EB-1, EB-2 NIW, and PERM-based cases. Alma reports a self-described approval rate above 98% for qualified cases, which is not a guarantee of any outcome, and a two-week turnaround for preparing documents once information is in the system, separate from USCIS processing time. Documents are uploaded into a secure platform, a dedicated attorney reviews qualifications against current USCIS standards, and applicants get real-time visibility into their case. Alma's services run up to the green card stage. Schedule a consultation to discuss eligibility.
Alma uses transparent flat-fee pricing. Employment-based green card categories such as EB-1A, EB-1B, EB-1C, and EB-2 NIW are priced at $10,000, dropping to $7,000 when filed with an already-approved O-1. A PERM labor certification is $8,000, a PERM-based I-140 is $4,000, an adult adjustment-of-status bundle is $2,000, and a consular green card is $2,500. These are flat attorney and platform fees. Government filing fees set by USCIS are billed separately because they vary by case.
Alma does not file naturalization (Form N-400) applications. Citizenship is a separate, later step handled directly with USCIS after the residence requirement is met. Alma's role is reaching and completing the green card stage.
Frequently Asked Questions
Yes. Permanent residence can be lost. USCIS explains that permanent residence can be revoked if an immigration judge issues a final order of removal, with the grounds set out in the Immigration and Nationality Act. A naturalized citizen cannot be deported and can lose citizenship only through a federal court proceeding on narrow grounds such as fraud.
In most cases, an applicant must be a permanent resident for at least 5 years before filing Form N-400, and may file up to 90 days early. For those married to and living with a US citizen, the requirement is 3 years. Applicants must also meet continuous residence, physical presence, good moral character, and English and civics requirements. See the USCIS naturalization requirements for the full list.
The Form N-400 filing fee is $710 online or $760 by paper, with a reduced $380 fee for households earning up to 400 percent of the Federal Poverty Guidelines who file on paper. USCIS reported a national median processing time of about 6.1 months in fiscal year 2024 and 5.7 months in fiscal year 2025, with monthly averages reaching roughly 7.9 months by early 2026 after a late-2025 filing surge. These uniform national estimates, which no longer vary by location, are available through the USCIS processing times tool.
No. With a green card, a person is already authorized to work for any employer without sponsorship, and both permanent residents and citizens are valid statuses for Form I-9. Naturalization is pursued independently. Its main employment effect is eligibility for jobs that legally require US citizenship, such as many federal positions and certain security-clearance roles.
Whether a person keeps a prior nationality depends on the laws of their home country, not on US immigration law. The US naturalization Oath of Allegiance, published by USCIS, includes a renunciation of allegiance to any foreign state.
