- USCIS continues to enforce a binary sex policy based strictly on birth records during 2026.
- Applicants face Requests for Evidence and delays when document markers do not match original birth certificates.
- The current framework prioritizes original birth proof over amended state documents or passports with ‘X’ markers.
(UNITED STATES) USCIS is still enforcing its binary sex policy in 2026, and that means applicants with a mismatch between their documents and their birth records face delays, Requests for Evidence, or stalled cases. The agency continues to recognize only male and female markers for immigration benefits, with no return of an “X” option or gender identity references.
That policy affects naturalization, green card filings, work permits, and citizenship certificates. It also reaches people with U.S. passports showing “X,” because USCIS gives priority to birth records or equivalent primary evidence, not later changes made on state documents.
USCIS sex marker rules now drive immigration filings
The agency’s current approach grew out of President Trump’s January 20, 2025, executive order, “Defending Women From Gender Ideology Extremism and Restoring Biological Truth to the Federal Government.” USCIS updated its Policy Manual on April 2, 2025, and that framework remains in place as of April 6, 2026. Applicants can review the agency’s official policy guidance and the main USCIS website for current filing instructions.
USCIS now treats sex as the male or female entry shown on a birth certificate issued at or near birth. If a birth certificate is unavailable, the agency looks to secondary proof, such as baptismal records, hospital affidavits, school records, or census documents that show sex at birth. The policy removes “gender” terminology from the adjudication framework and rejects medical certifications tied to transition history.
That matters because a mismatch can trigger closer review. VisaVerge.com reports that the agency’s 2026 vetting environment makes those mismatches harder to overlook, especially as DHS expands biometric checks and social media screening. In practice, a small inconsistency can stop an otherwise straightforward filing.
Forms most exposed to a sex and gender marker mismatch
The policy reaches major benefit requests, including:
- Form N-400, Application for Naturalization: The sex field must match the birth record.
- Form I-485, Application to Register Permanent Residence or Adjust Status: USCIS compares the filing against primary evidence.
- Form I-765, Application for Employment Authorization: The work permit request is reviewed against the same identity record.
- N-550 and N-560 certificates: Citizenship and naturalization certificates are issued with the sex marker supported by the record.
- Form I-129, Petition for a Nonimmigrant Worker: H-1B filings face more scrutiny where identity details do not match.
- Form I-589, Application for Asylum and for Withholding of Removal: Oral testimony can help when records are missing, but the birth sex rule still shapes the file.
The direct filing pages remain important. The Form I-485 page explains adjustment requirements, and the Form I-765 page covers work authorization filing details. Applicants using these forms need the same sex marker across the full packet.
A mismatch does not always lead to denial, but it often leads to a Request for Evidence. That notice slows the case and forces the applicant to explain the record trail in writing, then wait for a new review.
Evidence USCIS expects when records do not line up
Primary evidence comes first. USCIS wants the original birth certificate or an equivalent record created close to birth. If that record cannot be obtained, the agency asks for proof that the record does not exist and then turns to secondary evidence.
The strongest backup file usually includes:
- two or three older documents that show the same sex entry,
- affidavits from people with firsthand knowledge, such as a parent or midwife,
- and an official letter from the issuing authority when no birth record exists.
Applicants from countries with weak or unreliable civil registration systems often need to build that packet early. USCIS may accept the explanation, but it will not ignore a document trail that conflicts with the birth record it trusts most.
For many people, the toughest problem is a state-amended record or a passport that no longer matches the original certificate. USCIS still gives the original record control. That rule creates tension for transgender and nonbinary applicants who have updated identity documents elsewhere but not on the birth record USCIS uses.
Passports, amended birth certificates, and federal mismatch problems
USCIS does not defer to a U.S. passport with an “X” marker when the birth record shows male or female. It also gives less weight to amended state birth certificates than to the original record. That can lead to a federal mismatch even when state or consular records appear consistent.
The issue matters beyond one form. A green card printed after an I-485 approval may reflect the birth sex marker, not the marker on a passport. That difference can complicate reentry, I-94 updates, and later identity checks with CBP or ICE. It can also draw extra questions during naturalization interviews.
A real filing can stall quickly. An applicant with an “X” passport and an amended birth certificate may submit an I-485, only to receive a Request for Evidence asking for the original birth proof. The response clock then becomes the next barrier, not the visa number.
2026 vetting has made document review stricter
The sex marker policy has not changed, but the broader enforcement climate has made identity review sharper. DHS expanded biometric screening, launched a new USCIS Vetting Center on December 5, 2025, and widened social media review for many applicants. Those steps put more pressure on consistency between forms, travel records, and civil documents.
Employment cases feel that pressure fast. H-1B filings and related work authorization requests now face tighter checks, while the reduced 18-month validity for some EADs adds more renewal cycles. That means more chances for a mismatch to surface.
The same tension appears in the Visa Bulletin process. Applicants who can file now because a category is current still need clean identity evidence. A sex marker discrepancy can stop an otherwise current case before the interview stage.
What applicants are doing to avoid delays
People filing in 2026 are trying to line up every record before they send the packet. That means using the birth certificate as the anchor document, adding secondary proof where needed, and preparing a written explanation before USCIS asks for one.
A practical filing set usually includes:
- the original birth certificate, or an official record search letter,
- supporting secondary evidence,
- affidavits from firsthand witnesses, and
- a copy of every document that shows the same sex marker.
That approach matters because a Request for Evidence can add months to a case. It also matters for families, since terms in the Immigration and Nationality Act often follow birth sex language in family-based filings. For employers, the risk is slower hiring, more reverification work, and more uncertainty for sponsored workers.
USCIS has not reversed the policy, and no court ruling has forced a change as of April 2026. For now, the agency’s position remains fixed: the birth record controls the sex marker, and every filing must fit that framework.
