Yes, you can work with a green card, and you can do it without a separate work permit, without employer sponsorship, and without restriction on the type of job or the part of the country you take it in. Your permission to work is built into your permanent resident status itself. A handful of positions are reserved for U.S. citizens, and permanent residence brings tax and registration duties you should know about, but the default is simple: you work like any other resident of the United States.
Your Work Authorization Is Automatic
Federal regulations classify lawful permanent residents as “employment authorized incident to status.” In plain terms, the green card is your work permit. The regulation says this authorization applies “without restrictions as to location or type of employment.”1eCFR. 8 CFR Part 274a – Control of Employment of Aliens You do not apply for an Employment Authorization Document, and no employer can require one from you.
That freedom is what separates you from workers on temporary visas. An H-1B holder can only work for the employer who sponsored the petition. You have no such tie. Switch jobs whenever you want, hold two at once, leave the workforce for a year, come back — none of it affects your right to work.
Self-employment is fully open to you as well. USCIS confirms that permanent residents “may work in the United States without restriction,” which covers starting a business, contracting, or freelancing.2U.S. Citizenship and Immigration Services. Options for Alien Entrepreneurs to Work in the United States You register a business through your state’s business filing office the same way a citizen would.
Showing Your Card to a New Employer
Every U.S. employer has to complete Form I-9 for each new hire to verify identity and work authorization.3U.S. Citizenship and Immigration Services. Completing Form I-9 Your Permanent Resident Card (Form I-551) is a “List A” document, which means it satisfies both the identity and work-authorization requirements on its own.4U.S. Citizenship and Immigration Services. Form I-9 Acceptable Documents You do not need to add a driver’s license or passport.
Employers do not get to pick which document you show. Demanding specific extra documents beyond what the I-9 requires, or refusing a document that appears genuine on its face, can be an unfair immigration-related employment practice when done with discriminatory intent.5Office of the Law Revision Counsel. 8 USC 1324b – Unfair Immigration-Related Employment Practices If a hiring manager insists on a U.S. passport or birth certificate instead of your green card, that is a warning sign. The Department of Justice handles these complaints.6U.S. Department of Justice. Lawful Permanent Residents Employment Rights Under the Immigration and Nationality Act
Your Card Expires, But Your Right to Work Does Not
Standard green cards are printed with a 10-year expiration date. That date is about the piece of plastic, not your status. The regulation is explicit: “An expiration date on the Form I-551 reflects only that the card must be renewed, not that the bearer’s work authorization has expired.”1eCFR. 8 CFR Part 274a – Control of Employment of Aliens And once you have shown a valid green card at hire, your employer cannot come back later and demand a new document because the card’s date has passed.6U.S. Department of Justice. Lawful Permanent Residents Employment Rights Under the Immigration and Nationality Act
You still need to renew the physical card. File Form I-90 before the printed expiration. Once you properly file, USCIS automatically extends the card’s validity for 36 months from the expiration date, and the receipt notice serves as proof of continued status and work authorization while you wait for the replacement.7U.S. Citizenship and Immigration Services. USCIS Extends Green Card Validity Extension to 36 Months for Green Card Renewals
Conditional Green Cards Work Differently
If you got permanent residence through a marriage that was less than two years old at the time, your card is conditional and only valid for two years. You have to file Form I-751 in the 90-day window before it expires to remove the conditions. Missing that window can cost you your status entirely.8U.S. Citizenship and Immigration Services. Removing Conditions on Permanent Residence Based on Marriage A timely filing produces a receipt notice that extends your status and work authorization for 48 months.
When You Need Proof and Do Not Have a Card
If your card is lost, stolen, or expired while a renewal sits in processing, and you need to prove your status now for a job, ask USCIS for an ADIT stamp (also called an I-551 stamp). USCIS can issue it by mail after verifying your identity by phone in many cases, or bring you in to a field office. The stamp is valid for up to a year and works as temporary evidence of permanent residence.9U.S. Citizenship and Immigration Services.

The Jobs That Are Still Closed to You
USCIS puts the limit in one sentence: you may “work in the United States at any legal work of your qualification and choosing,” except that “some jobs will be limited to U.S. citizens for security reasons.”10U.S. Citizenship and Immigration Services. Rights and Responsibilities of a Green Card Holder (Permanent Resident) The categories are narrow.
Federal appropriations law generally requires that employees paid from federal funds be U.S. citizens, but there is an exception for lawful permanent residents who are actively seeking citizenship. If you fall in that group, many federal civilian jobs stay open to you.11Office of the Law Revision Counsel. 5 USC 3101 – General Authority to Employ Positions requiring a security clearance at the Top Secret level or above are almost always citizen-only regardless of that exception.
Elected office at the federal level requires citizenship under the Constitution, and nearly all state and local elected positions require it as well.
Defense and Export-Controlled Work Is Not Off Limits
One place green card holders get wrongly turned away is export-controlled work in defense, aerospace, and technology. Under the International Traffic in Arms Regulations and the Export Administration Regulations, permanent residents are classified as “U.S. persons,” the same as citizens. Employers do not need separate government authorization to share export-controlled technology or data with you. Those rules “don’t contain employment or hiring requirements” and “don’t require employers or recruiters…to limit jobs or recruitment to U.S. citizens.”12U.S. Department of Justice. How to Avoid Immigration-Related Discrimination When Complying With U.S. Export Control Laws Being rejected from an export-controlled role solely because you are not a citizen may itself violate anti-discrimination law.
Professional Licenses
Licenses for professions like nursing, law, engineering, and accounting are issued by the states, and requirements vary. Most states require applicants to be “lawfully present,” which green card holders easily satisfy. In practice, a permanent resident is in the same licensing position as a citizen in most states and most professions. A handful of states impose extra requirements for certain licenses, so check with your state’s licensing board before paying for exam prep.
Getting Paid: Social Security and Taxes
You need a Social Security Number to be on any employer’s payroll. If you did not request one on your immigration paperwork, you can walk into a local Social Security office with your green card and birth certificate (or a foreign passport if you cannot get a birth certificate) and apply. The card usually arrives within two to four weeks.13Social Security Administration. Apply for Your Social Security Card While Applying for Your Work Permit and/or Lawful Permanent Residency
Holding a green card also makes you a U.S. tax resident under the IRS “green card test.” That status applies for any calendar year in which you hold permanent residence, even part of one.14Internal Revenue Service. U.S. Tax Residency – Green Card Test You follow the same tax rules as a citizen, which means reporting worldwide income, not just what you earn inside the United States. File Form 1040 (or Form 1040-SR if you are 65 or older) by April 15.15Internal Revenue Service. Topic No. 851, Resident and Nonresident Aliens Foreign bank accounts, foreign rental income, and pensions from your home country all have to be reported, and depending on balances you may owe an FBAR or Form 8938 filing as well. New permanent residents get caught out on this often.
Your tax residency continues until your status is formally revoked, abandoned in writing, or terminated by a court, not when the physical card expires.14Internal Revenue Service. U.S. Tax Residency – Green Card Test
Selective Service for Men Under 26
Male green card holders between 18 and 25 must register with the Selective Service System within 30 days of their 18th birthday or within 30 days of entering the United States, whichever is later.16Selective Service System. Who Needs to Register Failing to register is a felony that carries up to $250,000 in fines and five years in prison, though prosecutions are rare. The consequence that catches people is later on: it can disqualify you from naturalizing.17Selective Service System. Benefits and Penalties
Do Not Lose the Status That Carries Your Right to Work
Everything above depends on keeping your permanent resident status. The most common way people put it at risk is time abroad. Stay out of the country for more than 180 consecutive days and you will be treated as “seeking admission” when you return, which triggers extra scrutiny. Stay out for more than a year continuously and there is a legal presumption that you have abandoned your residence.18U.S. Citizenship and Immigration Services. International Travel as a Permanent Resident You can rebut that presumption, but it is a hard argument.
If work or family will keep you abroad for more than a year, apply for a reentry permit on Form I-131 before you leave. It is valid for up to two years and removes the length of the absence as a factor. You have to file while physically present in the United States.
