Introduction to Form I-766: Your U.S. Work Authorization Card
If you’re an immigrant in the United States, getting official permission to work is a major step toward financial independence and long-term success. Form I-766, also known as the Employment Authorization Document (EAD) or work permit, is the card that proves you have authorization to work.
Whether you’re applying for a green card, seeking asylum, or on a temporary visa, this card is your key to legal employment.
In this guide, you’ll learn how to apply for work authorization using Form I-765, who qualifies for an EAD, how Form I-766 differs from Form I-765, what documents you need, and what to expect—so you can avoid delays and move forward with confidence.
What is Form I-766
Form I-766 is the Employment Authorization Document (EAD card) issued by USCIS after your Form I-765 application is approved. It serves as proof that you are legally allowed to work in the United States.
The card typically includes:
- Your name and photograph
- Employment authorization category
- Card expiration date
- Alien Registration Number (A-Number)
Employers rely on this card to verify your eligibility when completing Form I-9 (Employment Eligibility Verification), which is required before you begin working.

Form I-765 vs. Form I-766: What’s the Difference?
Many applicants confuse these two forms, but they serve different roles:
- Form I-765 is the application for employment authorization. If you want to legally work in the U.S., you must first file Form I-765 with U.S. Citizenship and Immigration Services (USCIS).
- Form I-766 is the actual physical card, also known as the Employment Authorization Document (EAD), that you receive once your I-765 application is approved. It proves you are authorized to work in the United States.
Here’s a quick breakdown:
| Form | Purpose | Who Uses It |
|---|---|---|
| I-765 | Apply for work authorization | Applicants requesting permission to work |
| I-766 | Proof of work authorization | Issued to approved applicants |

Why an EAD Card Is Important
An Employment Authorization Document (EAD) allows eligible noncitizens to work legally in the United States and access important opportunities.
Benefits include:
- Legal right to work while your immigration case is pending
- Access to employment opportunities and stable income
- Labor law protections, including fair wages and safe working conditions
- Identification use (accepted in some situations as a government-issued ID)
- Access to services, such as applying for a Social Security number or driver’s license (depending on state rules)
Working without authorization can negatively impact your immigration applications, so it’s important to maintain valid work authorization.
Who Is Eligible for an EAD Card?
You may qualify for an EAD if you are a noncitizen in a category authorized to work under U.S. immigration law.
Common eligible groups include:
- Applicants with a pending green card application (Form I-485 adjustment of status)
- Asylum applicants and asylees
- Refugees
- DACA recipients
- Temporary Protected Status (TPS) beneficiaries
- F-1 students (OPT or economic hardship)
- Spouses of certain visa holders such as H-1B (H-4), L-1 (L-2), and E-1/E-2
- K-1 fiancé(e) visa holders
- U visa, VAWA, or other humanitarian applicants
Eligibility depends on your specific category and supporting documentation. Always refer to USCIS guidance for your category.

When Should You Apply for a Work Permit (EAD)?
- First-time applicants: You can apply for an EAD as soon as you qualify based on your immigration status. Applying early can help you avoid delays in starting employment.
- Renewing your EAD: Submit your renewal application up to 6 months (180 days) before your current card expires to reduce the risk of interruptions in your work authorization. To understand renewal timelines and eligibility for continued work authorization, read our EAD renewal guide.
- Concurrent Filing: Many immigration categories allow you to submit your EAD application at the same time as other forms, such as a green card application.
- Automatic extension now longer: Some applicants who file a timely renewal of Form I-765 may be eligible for continued work authorization while their application is pending. However, eligibility and extension periods vary by category and current USCIS rules, so it’s important to review the latest guidance before relying on an automatic extension.
EAD Card Processing Time: What to Expect
When you apply for a work permit, USCIS processes your Form I-765.
Most applications take approximately 2 to 7 months or longer. Processing times vary widely based on:
- Your eligibility category (asylum, adjustment of status, DACA, etc.)
- USCIS workload
- Completeness of your application
- If you receive a Request for Evidence (RFE)
- Security/background checks for your category
After approval, your EAD card (Form I-766) is typically mailed within 2–4 weeks.
How to Apply for an EAD Card
Applying for an Employment Authorization Document (EAD) begins by filing Form I-765 with the U.S. Citizenship and Immigration Services. Follow these steps to complete your application:
- Check Your Eligibility: Make sure you qualify for a work permit under your immigration category—such as asylum, adjustment of status, DACA, or Temporary Protected Status (TPS).
- Gather Required Documents: Prepare copies of documents (mentioned above) that prove your identity, immigration status, and eligibility. If you are represented by an attorney, include Form G-28.
- Complete Form I-765: Fill out Form I-765 carefully and select the correct eligibility category, as this determines your work authorization.
- Pay the Filing Fee: Check the latest filing fee on the USCIS website. Payment options depend on whether you file online or by mail.
- Submit Your Application: You can file in two ways:
- Online through your USCIS account (recommended)
- By mail to the correct address listed in the I-765 instructions, based on your category
- Biometrics Appointment (If Required): Some applicants may be required to attend a biometrics appointment. USCIS will notify you if this step applies to your case.
- Track Your Case: After filing, use your receipt number to monitor your case status through the USCIS online case tracker.
- Get Your EAD by Mail: If your application is approved, your EAD card (Form I-766) will be mailed to you, typically within a few weeks after approval.
What Happens After You Receive an EAD Card?
Receiving your Form I-766 Employment Authorization Document (EAD card) is a major milestone—it means you are authorized to work in the United States. Here’s what to do next:
Apply for a Social Security Number (SSN)
If you did not request a Social Security number during your Form I-765 application, you should apply for one after receiving your EAD card.
An SSN is required for:
- Employment
- Filing taxes
- Accessing financial and government services
If you requested an SSN with your application, it will usually arrive separately by mail.
Complete Employment Verification (Form I-9)
Before starting a job, your employer must verify your identity and work authorization using Form I-9.
Your EAD card (Form I-766) is a List A document, which means it is sufficient on its own to prove both identity and work authorization.
Start Working (If Eligible)
In most cases, you can begin working once you receive your valid EAD card. Some applicants may have different rules depending on their category or renewal status.
Understand Your Responsibilities
Once you start working, you are generally required to:
- Follow federal and state tax laws
- Maintain valid work authorization
- Renew your EAD before it expires, if needed
What to Do If Your Work Permit (EAD Card) Is Lost or Stolen
Losing your Employment Authorization Document (Form I-766) can be stressful, but you can request a replacement through U.S. Citizenship and Immigration Services.
1. Make Sure You Still Have Valid Status
Before applying for a replacement, confirm that your underlying immigration status is still valid. Your eligibility to work must still be active.
2. File Form I-765 for a Replacement Card
If your EAD card is lost, stolen, or damaged, you must file a new Form I-765 and select the option for a replacement card.
You’ll typically need to:
- Pay the filing fee (unless exempt or eligible for a fee waiver)
- Provide proof of identity and immigration status
- Include copies of any previous EAD (if available)
3. If Your Card Was Not Delivered
If your EAD was approved but never arrived, you can submit a non-delivery inquiry through the USCIS website using your receipt number.
4. Correcting Errors on Your EAD
- If USCIS made the error: You may request a correction without filing a new application or paying a fee.
- If the error was yours: You will need to file a new Form I-765 and pay the required fee.
5. Keep Copies for Safety
Always keep copies of your EAD card and USCIS notices. This can make the replacement process faster and easier if your card is lost.
If your EAD is close to expiring, you should follow the renewal process instead. See our guide on how to renew your EAD (Form I-765) for step-by-step instructions.
U.S. Work Permit FAQs
1. How long does a work permit stay valid?
The validity of your EAD depends on your immigration category. Many applicants, such as those with pending adjustment of status (Form I-485), may receive an EAD valid for up to two years, while others may receive one-year or shorter validity periods. Always check your card’s expiration date and renew on time to avoid gaps in work authorization.
2. Can a work permit be used as a valid ID?
Your EAD card is a government-issued photo identification document and may be accepted in many situations, such as employment verification, opening a bank account, or interacting with certain agencies. However, acceptance can vary depending on the organization or purpose.
3. Is it possible to travel with an EAD card?
An EAD card does not serve as a travel document. To travel internationally and return to the United States, you must have the appropriate travel authorization, such as advance parole or a valid visa, depending on your immigration status.
4. If my visa allows me to work, do I still need an EAD card?
5. What is the difference between Form I-765 and Form I-766?
Form I-765 is the application used to request work authorization, while Form I-766 is the EAD card issued after approval. The card serves as proof that you are authorized to work in the United States.

Instead:
- You file Form I-765
