For many immigrants in the United States, a single card determines whether they can legally begin work — and when that card expires, so does the authorization that comes with it. Form I-766, the Employment Authorization Document, is the official card issued by U.S. Citizenship and Immigration Services (USCIS) to individuals who have been approved for work authorization in the United States. Understanding what it is, who receives it, how to obtain it, and what to do when it expires is an important part of managing work eligibility throughout an immigration journey.
What Form I-766 is
Form I-766 is the physical EAD card — commonly referred to as a work permit — that USCIS issues to eligible individuals following approval of a Form I-765, Application for Employment Authorization. The I-766 card confirms that the holder is legally authorized to work in the United States for the period shown on the card.
It is worth distinguishing between the two related forms. Form I-765 is the application — the request for work authorization submitted to USCIS. Form I-766 is the document issued after that application is approved. The card itself serves both as proof of employment authorization and as a government-issued photo identification accepted for a range of purposes beyond employment.
The I-766 card contains the holder’s full legal name, date of birth, photograph, Alien Registration Number (A-number), immigrant category code, card number, and validity and expiration dates. It also includes security features such as holographic images designed to prevent counterfeiting, as well as a machine-readable zone for quick identity verification.
Who receives Form I-766
Form I-766 is issued to individuals in a range of immigration categories who are eligible to apply for work authorization through Form I-765. Categories frequently associated with EAD issuance include:
● Adjustment of status applicants. Individuals who have filed Form I-485 to apply for a Green Card may receive an EAD under category C09, allowing them to work while their Green Card application remains pending.
● F-1 students on Optional Practical Training. Students on F-1 visas authorized for OPT receive an EAD.. STEM degree holders may receive an extension..
● H-4 visa holders. Qualifying spouses of H-1B visa holders who meet the applicable eligibility conditions receive an EAD under category C26.
● Asylees and refugees. Individuals with asylum status receive an EAD under category A05, and refugees under category A03.
● DACA recipients. Individuals granted Deferred Action for Childhood Arrivals status receive an EAD under category C33.
Each category has its own eligibility conditions and validity period. Applicants should confirm which category applies to their situation before filing Form I-765, as using the wrong category code is a frequently cited cause of processing delays.
How to obtain Form I-766
The process for obtaining an EAD card begins with filing Form I-765 with USCIS. The application must include all required supporting documentation for the applicable eligibility category, along with the correct filing fee. Once the application is processed and approved, USCIS issues the I-766 card and mails it to the address on file. Following approval of Form I-765, the EAD card typically arrives within approximately two weeks via USPS Priority Mail.
Processing times for Form I-765 vary by eligibility category and USCIS service center. Current estimates are available on the USCIS processing times page. Applicants generally may not begin working until the physical EAD card is in hand, unless they hold a separate valid work authorization or qualify for an applicable extension.
Common uses beyond employment
While employment authorization is the primary function of the I-766, the card is accepted as valid identification in a number of other contexts:
● Domestic air travel. The Transportation Security Administration recognizes the EAD as an acceptable form of identification for domestic flights.
● Driver’s license applications. The EAD may be used to establish identity when applying for a driver’s license at the Department of Motor Vehicles.
● Banking. Many financial institutions accept the EAD as proof of identity when opening a bank account.
● Social Security. The EAD may be used, along with other required documentation, when applying for a Social Security card.
Validity and renewal
The validity period of an I-766 card depends on the holder’s immigration status and eligibility category, and typically ranges from one to two years. When the card expires, so does the work authorization it represents — and the holder must file a new Form I-765 to renew.
Filing the renewal application well in advance of the expiration date is strongly advisable. Gaps in work authorization can prevent legal employment until a new card is received. For certain eligibility categories, a timely-filed renewal may qualify for an automatic extension of work authorization while the application is pending — though the categories and conditions for this extension are specific and should be confirmed directly on the USCIS automatic EAD extension page before relying on it for planning purposes.
If an EAD card is lost or stolen, a replacement may be requested by filing a new Form I-765 with the applicable fee and supporting documentation. Theft should also be reported to local law enforcement.
The value of legal guidance
Some immigrants are authorized to work incident to their immigration status — meaning their visa or status itself confers work authorization without a separate EAD application. This applies to holders of certain work visas such as the H-1B and L-1, as well as some dependent visa categories. Others must proactively apply for an EAD and carry it as proof of authorization for employers. For individuals who are uncertain whether they need an EAD, which category applies to their situation, or how their work authorization fits into a broader Green Card or visa strategy, consulting with experienced immigration counsel is frequently cited as the clearest path to avoiding errors that can disrupt employment eligibility.
