Do Green Card Holders Have Automatic Work Authorization?

Yes. Green card holders have automatic work authorization in the United States, built directly into their permanent resident status. Federal regulations classify lawful permanent residents as authorized to work “without restrictions as to location or type of employment,” so no separate work permit, employer petition, or government approval is needed to take a job, change jobs, or switch industries.¹

What Your Green Card Authorizes

Unlike workers on H-1B or other temporary visas, you do not need an Employment Authorization Document. Your green card itself is the work permit. There is no annual renewal of that authorization, no employer sponsorship, and no cap on how many jobs you can hold.

The authorization extends to self-employment. USCIS confirms that lawful permanent residents “may work in the United States without restriction,” which includes starting a business, freelancing, or working as an independent contractor.² You do not need a particular business entity or a separate permit to be self-employed; the same licensing rules that apply to U.S. citizens running a business apply to you.

Proving Your Eligibility to an Employer

Automatic work authorization does not mean automatic paperwork. Every new hire in the United States must show documents proving both identity and work authorization on Form I-9. Your green card (Form I-551) is a “List A” document, which means it satisfies both requirements in one card.³ If your physical card is being renewed or replaced, you can instead present a List B identity document (like a driver’s license) paired with a List C work-authorization document such as an unrestricted Social Security card, meaning one with no notation limiting employment.

Two other forms of temporary evidence work as List A documents. USCIS can place an I-551 stamp (an ADIT stamp) in your foreign passport, valid for up to one year.⁴ A machine-readable immigrant visa (MRIV) in your passport is also accepted as temporary List A evidence for one year from your admission date.⁵

If your card is lost, stolen, or damaged, the receipt showing you filed Form I-90 for a replacement counts as temporary proof of work authorization for 90 days from your hire date.⁶ Before that window closes you need to present the replacement card or another acceptable document. All documents must be original and unexpired; employers cannot accept photocopies.

Employers Cannot Reverify You When Your Card Expires

Something many green card holders do not realize: your employer is not allowed to reverify your work authorization when your green card expires. USCIS is explicit that employers “should not reverify” a permanent resident’s employment authorization and that “reverification is never required” when a Form I-551 expires.⁷ The expiration date on the card reflects that the card needs renewing, not that your authorization has ended.¹

The one exception is temporary evidence. If you were originally hired on an ADIT stamp, an MRIV, or an expired card paired with a conditional-status extension receipt, your employer must reverify when that temporary evidence expires.⁷ If you showed a standard green card at hire, that closes the book on verification.

When Your Card Expires or Goes Missing

Your permanent resident status does not expire when your card does. The card is proof of status, not the status itself. You still need valid documentation for new jobs and travel, so renew promptly.

Renewing a Standard 10-Year Card

When you file Form I-90 to renew an expiring or expired green card, USCIS issues a Form I-797 receipt notice that automatically extends the card’s validity for 36 months from the expiration date printed on the front.⁸ The expired card plus the receipt together serve as a valid List A document for Form I-9. This extension was increased from 24 to 36 months to account for processing backlogs, so keep the I-797 stapled to your expired card.

Conditional Residents Filing to Remove Conditions

If you received your green card through marriage (Form I-751) or an investment visa (Form I-829), your initial card is valid for only two years. When you file to remove conditions, the receipt notice now extends the card’s validity for 48 months from its expiration date.⁹ During that period you remain authorized to work and travel. If you already received a receipt with a shorter extension, USCIS will issue an updated notice if your case is still pending.

Lost or Stolen Cards

File Form I-90 for a replacement immediately. The filing receipt gives you 90 days of temporary documentation for employment purposes.⁶ If the replacement has not arrived within that window, you may need to visit a USCIS field office to request an I-551 stamp in your passport as a bridge. Do not wait until you need the card for a new job to discover it is missing.

The Narrow Set of Jobs That Still Require Citizenship

Your green card opens nearly every door in the U.S. labor market, but a small number of positions are off-limits.

Most competitive federal civil service jobs require U.S. citizenship under Executive Order 11935. Agencies can make exceptions when permitted by law and necessary for a specific role, but in practice those exceptions are rare and usually involve hard-to-fill technical or medical positions.

Standard security clearances are also closed to non-citizens. If your work requires access to classified information, you may qualify only for a Limited Access Authorization at the Secret level or below, tied to a specific project and cancelled when the project ends.¹⁰ Top Secret roles are effectively closed to anyone who is not a citizen.

One area where green card holders often have more access than they expect is defense contracting governed by the International Traffic in Arms Regulations. ITAR defines “U.S. person” to include lawful permanent residents, not just citizens.¹¹ Many defense-industry engineering and manufacturing roles that require ITAR-controlled access are open to you without an export license, even though some employers mistakenly screen out non-citizens across the board.

Protection Against Employer Discrimination

Federal law makes it illegal for an employer to discriminate against you in hiring, firing, or recruitment because of your citizenship status or national origin. The Immigration and Nationality Act specifically lists permanent residents as “protected individuals.”¹² Employers also cannot demand more or different documents than the law requires. If your green card looks genuine and relates to you, an employer who refuses it or insists on additional proof is committing what the law calls “document abuse.”

Two nuances are worth understanding. An employer is allowed to prefer a U.S. citizen over a permanent resident when both candidates are equally qualified. And your “protected individual” status has a shelf life: if you become eligible for naturalization and do not apply within six months, or if your application has been pending more than two years without active pursuit, you lose this specific protection.¹² Protection against national origin discrimination continues regardless.

You can file a charge with the Department of Justice’s Immigrant and Employee Rights Section within 180 days of the incident, electronically or by mail. IER runs a multilingual worker hotline at 1-800-255-7688.¹³ Employers with three or fewer employees are exempt.¹⁴

How You Can Lose the Work Authorization

Because work authorization is a feature of the status, losing the status ends the authorization. The most common way that happens quietly is through long absences from the United States.

An absence of more than 180 continuous days triggers additional scrutiny at re-entry. If you stay abroad for more than one year without a re-entry permit, there is a presumption you have abandoned your permanent residence. Officers weigh whether you kept a U.S. home, filed U.S. tax returns, maintained bank accounts and employment ties, and where your immediate family lived. Working for a foreign employer or voting in a foreign election are particularly damaging signals.

If you expect to be outside the United States for more than a year, file Form I-131 for a re-entry permit before you leave. The permit is valid for up to two years and removes length of absence as an abandonment factor, provided you return before it expires. Once permanent resident status is formally abandoned or revoked, your right to work in the United States ends immediately.
