An H-4 EAD cover letter is a one-page routing summary you place on top of your Form I-765 packet. It is not required by USCIS, but it tells the intake officer who you are, that you are filing under eligibility category (c)(26) as the H-4 spouse of an H-1B worker, which pathway makes you eligible, and exactly what documents are enclosed. Written well, it works as a table of contents for the packet and helps prevent misrouting at the lockbox.
Identify Your Eligibility Basis Before You Write
The letter has to name the basis for your eligibility, so settle that first. H-4 spouses qualify for an EAD through one of two routes tied to the H-1B spouse’s immigration history.
The first route is that your H-1B spouse is the primary beneficiary of an approved Form I-140, Immigrant Petition for Alien Workers. If the I-140 is approved, your letter references the I-140 receipt number and the I-797 approval notice.1U.S. Citizenship and Immigration Services. Employment Authorization for Certain H-4 Dependent Spouses
The second route applies when your H-1B spouse has been granted status beyond the six-year H-1B limit under the American Competitiveness in the Twenty-First Century Act (AC21), sections 106(a) and (b). This generally requires that a labor certification application or I-140 petition was filed at least 365 days before the extended H-1B period began. On this route, your evidence includes the H-1B spouse’s passports, prior I-94 records, current and prior I-797 notices for Form I-129, and documents establishing the AC21 basis.1U.S. Citizenship and Immigration Services. Employment Authorization for Certain H-4 Dependent Spouses
Either way, the eligibility category on Form I-765 is (c)(26), corresponding to 8 CFR 274a.12(c)(26), which identifies H-4 nonimmigrant spouses of qualifying H-1B workers as eligible for employment authorization.2eCFR. 8 CFR 274a.12 – Classes of Aliens Authorized to Accept Employment State that category on the letter so the officer can confirm the classification at a glance.
Information To Gather First
Before drafting, pull the details you will name in the letter. Your full legal name as it appears on your passport, date of birth, and your 11-character I-94 number from the CBP website.3U.S. Customs and Border Protection. I-94/I-95 Website From your H-1B spouse’s records, get the I-140 approval notice or the AC21 evidence described above, plus the receipt number from the most recent I-129 extension. That I-129 receipt number matters twice: your letter cites it, and its three-letter prefix determines which USCIS lockbox you mail to.
What To Put in the Cover Letter
Keep it to one page.
Header and Subject Line
Put your name, mailing address, phone number, email, and the date at the top. Below that, add a subject line beginning with “Re:” that names the filing. For example: Re: Initial Application for Employment Authorization (Form I-765), Category (c)(26). Swap “Initial” for “Renewal” if that is what you are filing. This one line tells the intake clerk what they are holding.
Body
The first paragraph states that you hold valid H-4 nonimmigrant status as the spouse of an H-1B visa holder and are applying for employment authorization under category (c)(26). Name your H-1B spouse and reference either the I-140 receipt number or the AC21 evidence, depending on your pathway. This gives the officer a direct verification trail without digging through exhibits.
The second paragraph is a brief bridge, one or two sentences, noting the enclosed Form I-765, supporting evidence, and filing fee. Do not re-summarize the evidence here. The enclosure list does that job.
Enclosure List
Close the letter with a numbered list of everything in the packet. A typical initial-application list:
- Form I-765, signed and dated
- Copy of your marriage certificate
- Copy of your passport biographical page
- Copy of your most recent I-94 record
- Copy of the H-1B spouse’s I-140 approval notice (Form I-797) or AC21 supporting evidence
- Copy of the H-1B spouse’s most recent I-129 approval or receipt notice
- Two identical passport-style color photographs
- Filing fee payment
- Form G-1145 (optional, for electronic notification of receipt)
Form G-1145 is a one-page form you can clip to the front of the packet to get a text or email when USCIS accepts the filing. It is not required, but the notification arrives faster than the mailed receipt and includes your case receipt number.4U.S. Citizenship and Immigration Services.

Assembling and Mailing the Packet
Packet Order
Cover letter on top, then Form I-765, then supporting evidence in the same order as your enclosure list. Use a binder clip or ACCO fastener, not staples, so USCIS staff can separate pages for scanning. If you are using Form G-1145, clip it to the very front.
Choose the Correct Lockbox
The mailing address depends on the three-letter receipt-number prefix on your H-1B spouse’s most recent I-797 for Form I-129, not your state of residence. Prefixes EAC, LIN, and MCT go to the USCIS Dallas lockbox. Prefixes WAC, SRC, and IOE go to the USCIS Phoenix lockbox. The exact street addresses differ for USPS versus courier delivery (FedEx, UPS, DHL).5U.S. Citizenship and Immigration Services. Direct Filing Addresses for Form I-765, Application for Employment Authorization Sending your packet to the wrong lockbox can mean rejection, so verify the prefix before you seal anything.
Filing Fee
USCIS updated its fee schedule in 2026 for statutory inflation adjustments. The I-765 filing fee changes periodically, so confirm the current amount on the USCIS fee page immediately before mailing. Applications arriving with the wrong fee get rejected.6U.S. Citizenship and Immigration Services. I-765, Application for Employment Authorization
Tracking and Receipt
Use a trackable method, whether USPS Priority Mail, FedEx, or UPS, and keep the tracking number. Within a few weeks of delivery, USCIS issues Form I-797C, Notice of Action, as your formal receipt. That notice carries your unique case receipt number for status checks.
Renewal Letters: The Automatic Extension Is Gone
If you are writing a renewal cover letter, one change dominates everything else. An interim final rule effective October 30, 2025, eliminated the automatic extension of EADs for renewal applicants. Renewals filed on or after that date do not automatically extend your existing EAD while USCIS processes the new one.7U.S. Citizenship and Immigration Services. DHS Ends Automatic Extension of Employment Authorization
In practice, if your current EAD expires before USCIS approves the renewal, you must stop working. There is no grace period. USCIS recommends filing renewals up to 180 days before your EAD expires to reduce the risk of a gap.7U.S. Citizenship and Immigration Services. DHS Ends Automatic Extension of Employment Authorization Even filing early does not guarantee no lapse, so coordinate with your employer.
For a renewal, change the subject line to Re: Renewal Application for Employment Authorization, add a copy of your expiring EAD (Form I-766) to the enclosure list, and reference your previous EAD receipt number in the body alongside the same eligibility information.
Filing the EAD With an H-4 Extension
If your H-4 status is also expiring, you can bundle Form I-765 with Form I-539 (Application to Extend/Change Nonimmigrant Status) and your H-1B spouse’s Form I-129 in one package.6U.S. Citizenship and Immigration Services. I-765, Application for Employment Authorization Filing together keeps the cases linked and historically produced faster adjudication.
USCIS recommends filing Form I-539 at least 45 days before your authorized stay expires.8U.S. Citizenship and Immigration Services. Application to Extend/Change Nonimmigrant Status When bundling, list all three forms in your cover letter and note the separate filing fees for each so the lockbox staff can split and route the forms correctly.
Mistakes That Trigger Rejection
Lockbox staff reject applications for clerical errors before an officer looks at the merits. The frequent ones:
- Wrong filing fee, including being a few dollars off from using last year’s schedule.
- Missing signature on Form I-765.
- Wrong lockbox address, because the filer used their home state instead of the I-129 receipt prefix.
- Photographs that are mounted, retouched, or digitally enhanced. Edited photos delay processing and can require a trip to an Applicant Support Center to verify identity.6U.S. Citizenship and Immigration Services. I-765, Application for Employment Authorization
- An old address on file. If you move after filing, update both USCIS and the U.S. Postal Service, because a lost notice can mean a missed appointment and, in some cases, refiling and paying the fee again.
The cover letter will not fix any of these on its own, but writing the enclosure list forces you to inventory the packet before it goes in the envelope. If your list says “filing fee” and there is no check inside, you catch it before USCIS does.
