Employment Authorization Documents carry a short code that looks technical but matters a lot. Are you (c)(9)? (c)(26)? What does the code on your card mean, and why does it matter to your employer? Forms and forums use these codes without much explanation.
As of October 31, 2026, this guide explains how the system works, lists the common codes for skilled immigrants and their families, and explains why your code matters.
- You enter one eligibility category in Part 2, Item Number 27, of Form I-765.
- (a) classes are authorized incident to status; (c) classes must apply.
- (c)(9) is for adjustment applicants, and (c)(26) is for certain H-4 spouses.
- (c)(3)(A), (B) and (C) cover pre-completion, post-completion and STEM OPT.
- A pending-case applicant may have a different code from someone already granted.
- EAD validity for (c)(9) applicants is now capped at 18 months.
How do the codes work?
They come from one regulation, 8 CFR 274a.12, which has three groups:
| Group | What the regulation says | What it means in practice |
|---|---|---|
| (a) | "Aliens authorized employment incident to status" | Work comes with the status, though some must still apply for a card |
| (b) | "Aliens authorized for employment with a specific employer incident to status or parole" | Tied to one employer, such as H-1B |
| (c) | "Aliens who must apply for employment authorization" | Must apply and be approved |
For (a), the regulation says these people may work "without restrictions as to location or type of employment." For (c), a person may accept work "subject to any restrictions stated in the regulations or cited on the employment authorization document."
Form I-765 asks for one code. "You must type or print your eligibility category in Part 2., Item Number 27., on Form I-765. Enter only one category number on the application" (USCIS, Instructions for Form I-765).
What are the common codes?
Here are those you are most likely to see in employment-based and student cases, from the current instructions:
| Code | Who it covers |
|---|---|
| (c)(9) | Applicants with a pending Form I-485 |
| (c)(26) | "Spouse of an H-1B Nonimmigrant" with qualifying status |
| (c)(3)(A) | "Pre-Completion OPT" |
| (c)(3)(B) | "Post-Completion OPT" |
| (c)(3)(C) | "24-Month Extension for STEM Students" |
| (a)(17) | Spouse of an E-1, E-2 or E-3 worker |
| (a)(18) | "Spouse of an L-1 Intracompany Transferee" |
| (c)(35) | "Principal Beneficiary of an Approved Employment-Based Immigrant Petition Facing Compelling Circumstances" |
| (c)(36) | Spouse or unmarried child of that principal |
| (a)(3) | Refugee |
| (a)(5) | Person granted asylum |
| (c)(8) | Person with a pending asylum application |
| (a)(12) and (c)(19) | Temporary Protected Status |
The full list is in the instructions, so use that if your situation is not here.
Why can pending and approved cases differ?
Because the basis differs. USCIS says "a person with a pending application for an immigration benefit or request might have a different category number than a person who was already granted the benefit or request." Its example: "a person with a pending asylum application may file an EAD application under category (c)(8); by contrast, the EAD category for a person already granted asylum is category (a)(5)" (USCIS, Instructions for Form I-765).
It also warns against filing under the wrong one. A refugee who is filing for a green card should "file Form I-765 under category (a)(3) as a refugee," and not under (c)(9). A wrong code can slow or sink your request, so check before filing.
What does the code change for you?
Several real things.
How long your card lasts. USCIS "updates the maximum validity period for initial and renewal EADs from 5 years to 18 months" for groups including "those with pending applications for adjustment of status under INA 245" (USCIS Policy Manual update, December 4, 2025). Other categories have their own limits.
Whether a renewal has any bridge. DHS's 2025 and 2026 rules ended automatic extensions for many categories for renewals filed on or after October 30, 2025. The regulation keeps the old rule under a heading for a "renewal application filed before October 30, 2025" (8 CFR 274a.13(d), eCFR). Our guide to the end of automatic EAD extensions covers which categories are hit.
Whether you are even required to hold the card. Some (a) classes "are authorized to be employed" as a condition of status, though the regulation requires many of them to apply for a document as proof. Do not assume, and check the specific paragraph.
Your restrictions. A (c)(3)(B) OPT card has a practical training purpose, with its own limits. A (c)(9) card is not limited to one employer, though your green card case has its own job rules. A (c)(26) card depends on the H-1B spouse's situation. Our guide to the H-4 EAD explains that last one, and our guide to the EAD while your I-485 is pending explains the (c)(9) card.
Why does an H-1B worker not have a code on a card?
Because H-1B work comes from the petition, not an EAD. The regulation places a "temporary worker or trainee (H-1, H-2A, H-2B, or H-3)" in group (b), which means authorized with a specific employer, so an H-1B worker normally shows an I-94 and approval notice rather than an EAD. If that worker later files an I-485, a (c)(9) card can be added on top, and the two are separate.
Where do you find the code?
On the card itself, usually in a field marked Category, and typically without the punctuation. So (c)(9) is usually printed as C09, and (c)(26) as C26. Your I-797 approval notice is also worth keeping, and it should identify the basis for the approval. Compare them when you receive the card.
If there is a mistake, USCIS has a correction process. Its EAD page says if a correction is needed, you may follow its procedure, and that you "must use the United States Postal Service (USPS) when returning your card" in that process (USCIS, Employment Authorization Document). Follow the page's current steps rather than old instructions.
Why does HR ask about the code?
Because of Form I-9. Your employer has to record what you show and when it expires, and in many cases must reverify you when the work authorization ends. An H-4 spouse, an OPT student and an I-485 applicant may look similar on paper, but their rules differ. Tell HR your renewal plans early, since a gap can stop you from working. If you hold an EAD and a valid H-1B at once, you may also need to explain which one you are using. Our guide to H-1B extensions covers that side of the question.
What about the filing fee?
It depends on the code and the form version. USCIS's current fee schedule, Form G-1055, lists fees for each. As of October 2026, our fee guide shows a work permit fee of $260 with a pending I-485, and there are others for OPT. Check the schedule on the day you file, since a wrong fee can lead to a rejection.
What this means for you
- Find your exact code on the card and on your approval notice.
- File under the correct code, and use only one on each Form I-765.
- Check whether your category has an 18-month limit.
- Do not count on an automatic extension for renewals.
- Tell HR your renewal timeline well before the expiration date.

Frequently asked questions
What is an EAD category code?
It is the legal class under which you are applying for, or holding, employment authorization. Form I-765 asks you to enter one category number in Part 2, Item Number 27. The instructions give the list, such as (c)(9) for someone with a pending I-485. On the card it often appears without parentheses, such as C09.
What does C09 mean on an EAD?
It means work authorization for someone who has filed an application for adjustment of status, under 8 CFR 274a.12(c)(9). USCIS can issue the card while the I-485 is pending. It is not itself a status. As of late 2025 the maximum validity is 18 months, and renewals filed on or after October 30, 2025 get no automatic extension.
What is the difference between (c)(26) and (a)(17)?
(c)(26) is for certain H-4 spouses of H-1B workers, who must apply for and get an EAD before working. (a)(17) is for spouses of E-1, E-2 and E-3 workers, and (a)(18) is for L-1 spouses, who are authorized incident to status. Check your I-94 and the regulation to confirm what proof you may use for Form I-9.
Where do I find my EAD category on the card?
It is printed on the card, usually in a Category field, as a code such as C09 or C26. The approval notice for Form I-765 may also show it. Check the code against your actual basis for work when you receive the card. If the code is wrong because of a USCIS error, use the USCIS procedure for correcting a card.
Can my EAD category change?
Your code depends on your basis. A person with a pending application may have a different category from someone already granted the benefit, as the instructions explain for asylum. So if your situation changes, you may need a new I-765 with the correct code. Do not assume one card covers a new basis, and ask an attorney about timing.
