Being legally authorized to work in the United States means that federal law allows you to perform the specific job you plan to accept. Your authorization may come from citizenship, lawful permanent resident status, another immigration status, an employer-approved classification, school-authorized practical training, or an Employment Authorization Document. A visa stamp or passport alone does not always prove that you may work.
Quick Answer
You are legally authorized to work in the U.S. when your citizenship, immigration status, approved employment classification, school authorization, or valid Employment Authorization Document permits the job. Check the conditions and expiration date that apply to your category. A visa stamp alone does not establish current employment authorization.
Key Takeaways
- Current work authorization and the need for future employer sponsorship are separate questions.
- For Form I-9, you choose one acceptable List A selection or one List B selection plus one List C selection.
- The employee completes Form I-9 Section 1 by the first day of paid work; the employer normally completes Section 2 within three business days.
- A visa stamp controls when you may request entry, while Form I-94 and your immigration category help determine your authorized stay and activities.
- Some eligible EAD renewal applicants receive an automatic extension of up to 540 days, but the extension does not apply to every category.
Legal information: This article provides general information, not legal advice. Immigration and employment-authorization rules depend on your exact category and can change. For advice about your situation, consult a licensed immigration attorney or a Department of Justice-recognized accredited representative.
What Counts as Work Authorization in the US?

Work authorization is legal permission to perform employment in the United States. The source and scope of that permission differ by category. Some people may work for almost any employer, while others may work only for a named employer, in an approved training program, or during a limited authorization period.
| Category | General work-authority scope |
|---|---|
| U.S. citizens and noncitizen nationals | Generally authorized to work without an immigration-related expiration date, although a limited number of jobs may lawfully require citizenship or other qualifications. |
| Lawful permanent residents | Generally authorized to work for any lawful employer. Expiration of the physical Green Card does not by itself end permanent resident status. |
| People authorized incident to status | Certain categories, such as refugees, asylees, and some dependent spouses, may be authorized to work because of their status or circumstances, even if they also choose to obtain an EAD. |
| Employer-specific nonimmigrant workers | H-1B, L-1, O-1, and similar classifications normally authorize only qualifying employment under the approved petition and status conditions. |
| EAD holders | May work within the rules and validity period of the EAD category, including any qualifying automatic extension. |
| F-1 and J-1 participants | May work only through employment specifically permitted by their student or exchange category, school, program sponsor, and any required USCIS approval. |
Work Authorization Versus Employer Sponsorship
Current work authorization answers whether you may legally work now. Sponsorship asks whether the employer must file or support an immigration petition now or later. You may therefore be authorized to work today but still need sponsorship in the future.
For example, an F-1 graduate with approved OPT may currently be authorized to work in a job related to the degree. However, that person may need an employer to sponsor another classification after OPT ends. A worker in H-1B status may be authorized for the petitioning employer but generally needs appropriate petition support to change employers or extend the employment period.
How to Check Your Work Eligibility
- Identify your exact category. Determine whether your authorization comes from citizenship, permanent residence, status, an approved petition, school authorization, a program sponsor, or an EAD.
- Check the controlling record. Depending on your category, this may be an EAD, Form I-94, Form I-20, Form DS-2019, Form I-797 approval notice, Green Card, or another official record.
- Confirm the permitted employer and activity. Some categories allow broad employment, while others limit you to a named employer, degree-related work, approved training, or a program activity.
- Check every relevant date. Review the authorization start date, expiration date, Form I-94 admitted-until date, school or program dates, and any receipt notice that may extend employment authorization.
- Confirm whether an extension applies. Do not assume that a pending application lets you continue working. Automatic extensions are category-specific.
- Ask the correct official or professional. F-1 students should contact their designated school official. J-1 participants should contact their program sponsor. Employer-specific workers may need the employer’s immigration team or legal counsel.
Warning: Do not begin a job before the required authorization takes effect. Filing an application, receiving a job offer, or holding a visa stamp does not automatically permit employment.
Documents That Prove You Can Work
When you start a job, you and your employer complete Form I-9. You choose which acceptable documents to present. Your employer generally cannot demand a Green Card, EAD, U.S. passport, Social Security card, or another specific document.
You may present either:
- One acceptable List A selection that establishes both identity and employment authorization; or
- One acceptable List B selection that establishes identity and one acceptable List C selection that establishes employment authorization.
| Document route | Common examples | Important detail |
|---|---|---|
| List A | Unexpired U.S. passport or passport card; Permanent Resident Card; Employment Authorization Document | A List A selection establishes both identity and employment authorization. Some List A selections consist of more than one document. |
| Status-specific List A combination | An unexpired foreign passport with Form I-94 or I-94A showing a qualifying work-authorized classification | The passport alone is not enough. The employment must be consistent with the classification, employer, and any petition restrictions. |
| COFA List A combination | Federated States of Micronesia or Republic of the Marshall Islands passport with Form I-94 or I-94A | The I-94 or I-94A must show qualifying admission under the Compact of Free Association. |
| List B plus List C | For example, a state driver’s license or identification card plus an unrestricted Social Security card | List B proves identity. List C proves employment authorization. A Social Security card marked with an employment restriction is not the unrestricted List C card. |
Normally, you must present original acceptable documents. A certified copy of a birth certificate may be acceptable, and certain official receipts may temporarily replace a lost, stolen, or damaged document. Qualifying E-Verify employers may use the Department of Homeland Security’s authorized alternative procedure for remote document examination.
Pro Tip: Review the official Lists of Acceptable Documents before your first day. Present only the document selection you choose. You do not need to provide a List A document together with List B and List C documents.
Use Form I-9 and E-Verify

Form I-9 and E-Verify serve related but different purposes. Every covered U.S. employer must complete Form I-9 for a new employee hired for pay. E-Verify is an electronic system used by enrolled employers to compare Form I-9 information with government records.
Form I-9 Essentials
- The employee completes Section 1. Complete and sign it after accepting the job offer and no later than your first day of paid employment.
- The employee presents acceptable documents. You choose one List A selection or one List B plus one List C selection.
- The employer completes Section 2. The employer normally examines and records the documents within three business days after your first day of work for pay.
- The employer retains the form. Form I-9 is generally kept by the employer rather than routinely filed with USCIS.
- Temporary authorization may require reverification. The employer may need to complete Supplement B before time-limited authorization expires.
Employers do not normally reverify U.S. citizens or noncitizen nationals. They also do not reverify a lawful permanent resident merely because the Permanent Resident Card later expires. Different rules can apply when the employee originally presented temporary evidence of permanent residence.
E-Verify Checks
An enrolled employer creates an E-Verify case after completing Form I-9. The case must normally be created no later than the third business day after the employee starts work for pay.
| Step | What happens |
|---|---|
| 1. Form I-9 is completed | The employer uses information from the completed form and the document selection presented by the employee. |
| 2. The employer creates a case | E-Verify compares the submitted information with records available to the Department of Homeland Security and Social Security Administration. |
| 3. The system returns a result | The result may confirm employment authorization or identify a mismatch that requires notice and an opportunity to respond. |
People age 18 or older who are physically in the United States may voluntarily use myE-Verify Self Check. Self Check can help identify a record mismatch before starting a job, but it is not an employment-authorization document and does not replace Form I-9 or the employer’s E-Verify case.
Employee Rights During Form I-9 and E-Verify
- Your employer generally cannot specify which acceptable Form I-9 documents you must present.
- Your employer cannot demand more documents than the Form I-9 process requires because of your citizenship, immigration status, or national origin.
- An employer should not use E-Verify to screen applicants before hiring them.
- An E-Verify mismatch does not automatically mean that you are unauthorized to work.
- If you choose to resolve a mismatch, the employer must follow the required notice and referral process and generally cannot take adverse action based only on the unresolved mismatch.
The Department of Justice provides more information about worker rights during employment verification.
Common Visa Paths for U.S. Jobs

The correct path depends on the job, employer, qualifications, immigration history, and intended length of employment. The following are common examples, not a complete list.
| Classification or program | General purpose | Main employment limit |
|---|---|---|
| H-1B | Specialty-occupation and certain related professional employment | Employment is generally tied to the petitioning employer, approved position, validity period, and H-1B rules. |
| L-1A or L-1B | Transfer from a qualifying foreign organization to a related U.S. organization | The worker may perform only qualifying employment for the approved organization. L-1A covers qualifying managers or executives; L-1B covers specialized-knowledge employment. |
| O-1 | Employment for people who meet the extraordinary-ability or extraordinary-achievement requirements | Work must remain within the approved petition, employer or agent arrangement, events, and validity period. |
| F-1 CPT or OPT | Practical training connected to an eligible academic program or field of study | CPT requires school authorization before work begins. OPT requires a DSO recommendation and USCIS authorization, including an EAD. |
| J-1 exchange visitor | Participation in an approved educational and cultural exchange category | A J-1 participant may perform only activities allowed by the exchange category, Form DS-2019, regulations, and designated program sponsor. |
A visa stamp placed in a passport is principally a travel document that allows you to request admission at a U.S. port of entry. It does not by itself determine how long you may remain or whether you may work. After admission, the Form I-94 record and your category’s conditions are critical.
Work Authorization Tips for F-1 Students
F-1 status does not provide unrestricted permission to work. Before accepting employment, confirm the job type, authorization source, start date, permitted hours, and reporting requirements with your designated school official.
Curricular Practical Training
- CPT must be an integral part of the established curriculum and directly related to your major area of study.
- Your designated school official must authorize the specific CPT employment in SEVIS and on Form I-20 before you start working.
- CPT may be part-time or full-time.
- Twelve months or more of full-time CPT generally makes you ineligible for OPT at the same educational level. Part-time CPT does not create that bar.
Optional Practical Training
- OPT employment must relate directly to your major area of study.
- You may generally receive up to 12 months of OPT at each higher educational level.
- Your designated school official must recommend OPT and issue an updated Form I-20.
- You must file Form I-765 with USCIS and receive the EAD before beginning OPT employment.
- Do not start before the EAD start date, even if the application is approved earlier.
The 24-Month STEM OPT Extension
An eligible student may apply for a 24-month STEM OPT extension. The qualifying degree and employment must meet STEM OPT requirements. The employer must participate in E-Verify, and the student and employer must complete Form I-983.
If USCIS receives a timely and properly filed STEM OPT extension application, the student may generally continue qualifying employment for up to 180 days after the current post-completion OPT EAD expires while USCIS decides the application. This STEM-specific continuation rule is separate from the general EAD automatic-extension framework.
Review the official ICE practical-training guidance and speak with your designated school official before changing employers, reducing hours, becoming unemployed, or traveling.
How to Answer Work-Authorization Questions on a Job Application
Employers commonly ask two separate questions:
- Are you legally authorized to work in the United States?
- Will you now or in the future require employer sponsorship?
Answer both truthfully based on your current authorization and the support you expect to need. Do not describe yourself as permanently authorized when your permission is time-limited or restricted to another employer.
| Situation | Current authorization answer | Sponsorship answer |
|---|---|---|
| U.S. citizen, noncitizen national, lawful permanent resident, refugee, or asylee | Generally “Yes.” | Generally “No” for immigration-related employer sponsorship. |
| Valid EAD holder | Generally “Yes” while the category authorizes the offered employment. | Depends on the underlying category and whether continued authorization will require employer support. |
| F-1 student with approved OPT | “Yes,” for qualifying employment during the authorized OPT period. | Often “Yes” for future sponsorship if you expect to continue after OPT or STEM OPT ends. |
| H-1B, L-1, O-1, or another employer-specific worker | “Yes” only for employment permitted by the applicable status and petition. | Appropriate employer petition support will generally be needed for a new employer, extension, or different classification. |
| No current employment authorization | “No.” A pending plan or possible future application is not current authorization. | “Yes,” if an employer petition or other employer support would be required. |
Note: A concise answer is usually enough during the application stage. Form I-9 document review occurs after hiring, and the employer generally must let you choose which acceptable documents to present.
What to Do When Work Authorization Expires
Start by identifying which document or authorization is ending. The correct action may be an EAD renewal, an employer-filed extension petition, a school recommendation, a program extension, or another status-specific filing. Form I-765 is not the correct renewal method for every worker.
Check Which Authorization or Record Expires
Review all records that apply to your category:
- EAD: Shows a card validity period, subject to any qualifying extension.
- Form I-94: Shows the admitted-until date or duration-of-status notation and classification.
- Form I-797: May show petition or application approval and related validity dates.
- Form I-20: Records F-1 program and practical-training information.
- Form DS-2019: Records the approved J-1 exchange program and dates.
- Visa stamp: Shows when the visa may generally be used to request admission, not the authorized duration of a current stay.
File the Correct Renewal or Extension Early
Eligible EAD holders normally request renewal with Form I-765. USCIS filing windows and evidence differ by eligibility category, so follow the current form instructions instead of relying on one deadline for every applicant.
Workers in H-1B, L-1, O-1, and similar employer-specific classifications generally rely on an employer-filed Form I-129 petition or another category-specific process rather than renewing work authorization through a routine EAD application. F-1 CPT requires school authorization, while OPT and STEM OPT require the applicable DSO recommendation and USCIS filing.
Check Whether an Automatic Extension Applies
DHS permanently increased the automatic-extension period from up to 180 days to up to 540 days for certain eligible EAD renewal applicants. However, an expired card and a pending Form I-765 do not automatically qualify every applicant.
General eligibility normally requires:
- A timely filed renewal application before the current EAD expires;
- An EAD category included in the automatic-extension rules;
- The required category match between the expiring EAD and receipt notice, subject to limited exceptions such as certain Temporary Protected Status filings; and
- Valid evidence showing the extension, such as the expired EAD together with the qualifying Form I-797C receipt notice and any additional category-specific document.
Check the current USCIS automatic EAD extension page for the eligible categories and required evidence.
Notify Your Employer and Complete Reverification When Required
Tell the appropriate employer representative before time-limited authorization expires. Provide acceptable proof of continued authorization, an eligible automatic extension, or a new authorization document by the required date.
The employer may complete Form I-9 Supplement B to reverify expiring employment authorization. You may choose any acceptable List A or List C documentation permitted for reverification. The employer generally cannot insist that you renew or present the same document used when you were hired.
Warning: Do not continue working merely because a renewal application is pending. Confirm that your category provides continued authorization and that you possess the required evidence. If no extension applies, employment must stop when authorization ends.
Plan for Travel and Visa Timing
Travel and employment authorization involve related but separate documents. A visa stamp may expire while you remain lawfully in the United States, provided your authorized stay and status remain valid. Conversely, an unexpired visa stamp does not permit you to remain after your authorized stay ends or to perform employment that your status does not allow.
Before international travel:
- Check your passport validity, visa requirements, and Form I-94 after every entry.
- Confirm that your petition, Form I-20, Form DS-2019, EAD, and travel endorsement remain valid where applicable.
- Determine whether departure could affect a pending extension, change-of-status request, adjustment application, advance-parole need, or practical-training authorization.
- Allow time for visa appointments, security checks, administrative processing, and document delivery.
- Ask your designated school official, J-1 sponsor, employer immigration team, or legal representative to review category-specific travel risks.
The U.S. Department of State explains the difference between visa validity and authorized stay.
Frequently Asked Questions
How should I answer “Are you legally authorized to work in the United States?”
Answer “Yes” only when you currently have authorization that covers the offered employment. If your authorization is temporary or employer-specific, answer any separate sponsorship question truthfully. A pending application or future plan is not current authorization.
What does “legally authorized to work” mean?
It means U.S. law currently permits you to perform the job. The permission may come from citizenship, permanent residence, another status, an approved employer-specific classification, school-authorized training, an exchange program, or an EAD.
How do I know whether I am authorized to work in the US?
Identify your immigration or citizenship category, check the document or record that controls employment, confirm the permitted employer and activity, and review the start and expiration dates. Seek category-specific guidance if any condition is unclear.
What should I put for work authorization on an application?
Answer the exact question asked. You may state that you are currently authorized to work, whether the authorization has limits, and whether you will need employer sponsorship now or later. Do not claim permanent or unrestricted authorization when your category is temporary or employer-specific.
Can an employer require me to show a Green Card or EAD?
Generally, no. For Form I-9, you choose one acceptable List A selection or one List B plus one List C selection. An employer generally cannot request a specific document or demand extra documents because of your citizenship, immigration status, or national origin.
Does an expired Green Card mean I am no longer authorized to work?
Not by itself. Expiration of the physical card does not normally end lawful permanent resident status. You may need valid evidence for travel, identity, or a new Form I-9, and a receipt notice or temporary I-551 evidence may extend or document the card’s validity.
Does E-Verify replace Form I-9?
No. An enrolled employer completes Form I-9 first and then creates the E-Verify case using information from the form. Voluntary Self Check also does not replace Form I-9 or serve as an employment-authorization credential.
Conclusion
You are legally authorized to work in the United States only when your citizenship, status, petition, school or program authorization, EAD, or other qualifying basis permits the job. Check the employer, activity, and expiration limits that apply to your category. Complete Form I-9 on time, choose your own acceptable documents, and never assume that a visa stamp or pending application provides permission to work.
If your authorization is temporary, review the correct renewal or extension process early. Confirm whether an automatic extension applies, keep your employer informed when reverification is required, and obtain category-specific advice before changing jobs or traveling internationally.
