Understanding U Visa Derivative Status
USCIS doesn't automatically extend U visa protection to your family when you receive U-1 status. Derivative status for qualifying family members — called U-2, U-3, U-4, or U-5 depending on the relationship — requires a separate filing step, either as part of your initial I-918 petition or afterward through Form I-918 Supplement A. The difference between filing simultaneously and filing later is procedural, not substantive, but it affects timing and approval patterns significantly.
U visa derivative status exists to keep families together when the principal applicant is assisting law enforcement in a qualifying criminal investigation. The category covers spouses, children, parents (if the principal is under 21), and unmarried siblings under 18 (also if the principal is under 21). These relationships are statutory — stepchildren and adoptive children qualify if the legal relationship existed before the child turned 18, but extended relatives and adult siblings do not.
Who Qualifies as a U Visa Derivative
Eligibility for derivative status depends on the relationship to the principal U visa applicant at the time of the principal's petition filing, with one exception for spouses acquired after approval. Children of the principal applicant qualify automatically if unmarried and under 21. This is U-3 status. Spouses qualify as U-2 derivatives. If the principal applicant is under 21 when filing Form I-918, parents qualify as U-4 derivatives and unmarried siblings under 18 qualify as U-5 derivatives. Once the principal turns 21, those two categories close — parents and siblings cannot be added afterward.
The relationship must be documented through civil records. USCIS requires birth certificates for parent-child relationships, marriage certificates for spouses, and court orders or adoption decrees for step-relationships and adoptions. If the principal is under 21 and lists parents or siblings, proof of the principal's age and the sibling's age and marital status is mandatory. Translations are required for documents not in English, along with a translator certification.
One common question is whether a spouse married after U visa approval can qualify. The answer is yes, but only through a separate I-918 Supplement A filing after the marriage occurs, and only if the principal applicant already holds U-1 status at the time of the new marriage. Spouses acquired while the principal was still in the waiting period before approval do not have a filing path until the principal's status is granted.
Form I-918 Supplement A — The Derivative Filing Mechanism
Form I-918 Supplement A, Petition for Qualifying Family Member of U-1 Recipient, is the USCIS form that requests derivative status for eligible relatives. It can be filed in two ways: attached to the principal's initial I-918 petition, or filed separately afterward if the principal already holds approved U-1 status. There is no filing fee for Supplement A in either scenario.
When filed with the principal petition, Supplement A is processed together with the I-918. If the principal is approved for U-1 status, the derivatives listed on Supplement A are approved simultaneously unless USCIS identifies an independent ground of inadmissibility affecting the derivative. The principal's approval does not cure a derivative's criminal history, fraud finding, or immigration violation — each derivative is evaluated on admissibility separately, and waivers may be required.
When filed after the principal's approval, Supplement A is adjudicated as a standalone petition. The principal must already be in U-1 status, not merely approved and waiting for a visa number. USCIS confirms the principal's current status, the validity of the relationship, and the derivative's admissibility. Processing times for post-approval Supplement A filings vary by service center, and as of 2026, USCIS does not publish separate processing estimates for derivative petitions — applicants should monitor case status online or consult the agency's general I-918 processing page.
Filing Derivatives at the Time of the Principal Petition
The clearest path is to list all qualifying family members on Supplement A when the principal files Form I-918. This is the simultaneous filing route. Each derivative gets one Supplement A form, accompanied by relationship documentation and two passport-style photos. If the principal is claiming victimization that occurred while under 21 and is now over 21 at filing, derivatives in the parent and sibling categories must still have been under the qualifying age threshold at the time the principal was victimized — the statutory snapshot freezes there.
Because the principal I-918 petition can take years to adjudicate, the derivative's circumstances may change during the wait. A child derivative who turns 21 while the petition is pending is protected by the Child Status Protection Act if they were under 21 when the principal filed. The age locks at filing. A derivative who marries while the principal petition is pending loses eligibility — U derivative categories require the child to remain unmarried through approval. If a listed derivative marries, USCIS will deny that individual's Supplement A even if the principal is approved.
Simultaneous filing does not require the derivatives to be in the United States. They can be abroad, and if the principal is approved, they apply for U visas at a U.S. consulate using the approved Supplement A. Consular processing for U derivatives follows the same DS-160 procedures as other nonimmigrant visa categories, but the consular officer's discretion is limited — the relationship and admissibility were already evaluated by USCIS.
Filing Derivatives After the Principal's U-1 Approval
If the principal did not list a qualifying family member on the initial I-918, or if a new qualifying relationship arises after approval, Supplement A can be filed separately. The principal must hold valid U-1 status at the time of filing. This is the post-approval or standalone Supplement A filing.
Common scenarios include a principal who marries after receiving U-1 status, or a principal who initially filed alone and later decides to bring children or a spouse to the U.S. USCIS requires proof of the principal's current U-1 status (a copy of the approval notice or current Employment Authorization Document showing U-1 category), proof of the relationship, and the derivative's admissibility documentation.
Post-approval filings carry one procedural advantage: the derivative may apply for advance parole (Form I-131) while Supplement A is pending, allowing travel without abandoning the application. Derivatives listed on the initial petition and waiting years for the principal's approval generally cannot travel until the petition is decided.
Here's the Honest Answer: Derivative Eligibility Does Not Extend Indefinitely
Let's be direct: the window for derivative filing is not open-ended. If the principal applicant ages out of the under-21 category after filing Form I-918, parents and siblings listed at filing are protected, but new parents or siblings cannot be added later. If a qualifying child marries while the petition is pending, that derivative is ineligible even if the principal is approved. And if the principal's U-1 status expires or is terminated, the ability to file new Supplement A petitions ends — derivatives must be filed while the principal holds valid status.
The protection flows from the principal's status. Once the principal adjusts to lawful permanent residence under INA 245(m) after three years in U-1 status, the derivative filing route through Supplement A closes. At that point, family members must pursue immigration benefits through standard family preference categories, which carry per-country caps and multi-year backlogs. Filing derivatives before the principal adjusts preserves the faster, cap-exempt U derivative path.
Documentation Requirements for Derivative Petitions
| Document Type | Purpose | Common Deficiency |
|---|---|---|
| Birth certificate (child derivative) | Proves parent-child relationship and child's age | Missing translation or incorrect name spelling creates RFE |
| Marriage certificate (spouse derivative) | Proves marital relationship and that marriage occurred while principal held U-1 status (post-approval filings) | Divorce decree from prior marriage not included when required |
| Birth certificate (parent/sibling derivative) | Proves family relationship and that principal was under 21 at victimization | Principal's age at victimization not documented separately |
| Two passport photos per derivative | Biometric identification per USCIS photo requirements | Photos older than 30 days or incorrect background color |
| Principal's U-1 approval notice (post-approval filings) | Confirms principal holds valid status authorizing derivative filing | Notice expired or principal already adjusted to LPR |
| Form I-192 (if derivative is inadmissible) | Waives grounds of inadmissibility that would bar approval | Filed without supporting waiver justification or hardship evidence |
USCIS will issue a Request for Evidence if required documents are missing or insufficient, but RFEs delay processing by months. Filing a complete Supplement A package the first time avoids that cycle.
What If the Principal's I-918 Is Still Pending After Years?
U visa petitions face a statutory cap of 10,000 principal approvals per fiscal year. When the cap is reached, approved petitions are placed on a waiting list and granted deferred action and work authorization until a visa number becomes available. Derivatives listed on the petition receive the same deferred action and work authorization as the principal while waiting. This is often called "waitlist status."
Derivatives in waitlist status can remain in the U.S. lawfully, renew their employment authorization annually, and apply for advance parole to travel. They are not in U-2/U-3/U-4/U-5 status yet — that status is granted only when a visa number becomes available and the petition fully approves. But the practical protections are nearly identical. The risk is that a derivative who marries while on the waitlist will lose eligibility when the petition finally adjudicates, because the unmarried requirement applies at approval, not at filing.
What If a Derivative Has a Criminal History or Prior Immigration Violation?
Derivative status does not waive inadmissibility automatically. If a derivative has a criminal conviction, fraud finding, prior removal order, or unlawful presence exceeding 180 days, USCIS evaluates those grounds the same way it would for any nonimmigrant applicant. Most grounds of inadmissibility can be waived through Form I-192, Application for Advance Permission to Enter as a Nonimmigrant, filed alongside or after Supplement A.
The waiver standard is discretion — USCIS weighs the severity of the ground of inadmissibility, the hardship to the principal U visa holder if the derivative is denied, rehabilitation evidence, and U.S. ties. A derivative's denial does not affect the principal's status, but it separates the family. Filing the I-192 waiver proactively, with detailed hardship declarations and supporting evidence, improves approval odds significantly.
What If the Principal Adjusts to a Green Card Before Filing for Derivatives?
Once the principal adjusts status to lawful permanent residence under INA 245(m), the U derivative pathway closes. The principal can no longer file Form I-918 Supplement A for qualifying family members. At that point, the only route is a standard family-based immigrant petition (Form I-130) as a green card holder petitioning for a spouse or unmarried child, which places the derivative in the F2A preference category. F2A currently carries a multi-year wait depending on the derivative's country of birth, and it is subject to per-country limits.
This is why many principals delay adjustment until derivatives are approved or at least filed for. The statute requires three years of continuous physical presence in U-1 status before adjustment eligibility, so the timing window is known. Derivatives should be filed well before the principal reaches the three-year mark if family unity is the priority.
Comparing Initial vs. Post-Approval Derivative Filing
| Filing Method | Timing | Advantages | Limitations |
|---|---|---|---|
| Simultaneous (with principal I-918) | Filed at the same time as principal petition | Derivatives approved when principal approves; no second waiting period; protects against age-out and cap delays | Derivatives wait years if principal petition is delayed or waitlisted; cannot add derivatives who enter the picture after filing |
| Post-approval (standalone Supplement A) | Filed after principal already holds U-1 status | Covers new relationships (spouse acquired after approval); faster processing because principal status is confirmed | Requires principal to hold valid U-1 status; cannot be used if principal already adjusted to green card; derivatives start from zero on processing time |
| Consular processing (derivatives abroad) | After Supplement A is approved, whether filed simultaneously or post-approval | Derivatives do not need to be in the U.S. to benefit; lawful visa issuance at consulate | Requires travel to home country for interview; consular delays vary by post; reentry not guaranteed if derivative has prior immigration violations |
The bottom line: filing derivatives simultaneously with the principal petition locks in eligibility and avoids timing gaps, but post-approval filing is the only option for relationships formed after the principal's approval.
Work Authorization and Travel for U Derivatives
Approved U derivatives (U-2, U-3, U-4, U-5) receive employment authorization incident to status — no separate EAD application is required. The I-94 showing U derivative status is sufficient work authorization. Derivatives on the waiting list receive deferred action and must file Form I-765 to obtain an EAD, renewable annually while waiting for visa number availability.
U derivatives may travel on advance parole (Form I-131) while their Supplement A is pending or while on the waitlist. Approved U derivatives holding valid status travel on their U visa. Leaving the U.S. without advance parole while Supplement A is pending abandons the application, and USCIS will deny it. This is a bright-line rule — consult counsel before any international travel if a derivative petition is in process.
The Path from U Derivative Status to a Green Card
U derivatives are eligible to adjust status to lawful permanent residence under the same INA 245(m) provision as the principal. The derivative must have been physically present in the U.S. for a continuous period of at least three years since being admitted in U derivative status, and must not have unreasonably refused to cooperate with law enforcement requests related to the principal's qualifying criminal investigation.
In practice, cooperation is rarely an issue for derivatives — the requirement ties to the principal's underlying case. The three-year clock starts when the derivative is admitted in U-2/U-3/U-4/U-5 status, not when Supplement A was filed or approved. Time spent in deferred action on the waiting list does not count toward the three years. Adjustment through this route does not require a separate immigrant petition or labor certification, and it is not subject to per-country caps — it is a direct path.
Common Errors in Derivative Filings
USCIS issues RFEs or denies Supplement A petitions most often for these errors: filing for a derivative relationship that does not qualify (adult sibling, grandparent, fiancé); filing after the principal has already adjusted to LPR status; listing a married child as a derivative; failing to include a waiver when the derivative is inadmissible; submitting a Supplement A without proof that the principal holds current U-1 status (post-approval filings); and using expired or incorrect photos.
Another frequent issue is name discrepancies. If the derivative's name on the birth certificate does not match the name on the passport or other identity documents, USCIS will request an explanation and legal name-change documentation. Solve this before filing by obtaining a court order or corrected civil document if the discrepancy is due to clerical error.

Frequently Asked Questions
Can I add my spouse to my U visa petition if I married after my I-918 was already approved? ▼
Yes. File Form I-918 Supplement A separately for the new spouse after the marriage, as long as you hold valid U-1 status at the time of filing. Spouses acquired after U-1 approval qualify as derivatives, but you cannot add them if you have already adjusted to lawful permanent residence.
Do my children automatically get U visas when I am approved for U-1 status? ▼
No. U visa protection for children is not automatic. You must list them on Form I-918 Supplement A, either when you file your initial I-918 petition or afterward if you already hold U-1 status. Children qualify as U-3 derivatives if they are unmarried and under 21.
What happens if my child turns 21 while my U visa petition is pending? ▼
The Child Status Protection Act protects your child's eligibility if they were under 21 when you filed Form I-918. Their age locks at the filing date. However, if the child marries while the petition is pending, they lose eligibility even if the principal petition is approved.
Can I file for my parents as U visa derivatives if I am over 21? ▼
No. Parents qualify as U-4 derivatives only if the principal applicant was under 21 at the time of filing Form I-918. Once you turn 21, you cannot add parents to your petition, and parents listed before you turned 21 are protected only if they were listed at filing.
Is there a filing fee for Form I-918 Supplement A? ▼
No. USCIS does not charge a filing fee for Form I-918 Supplement A, whether filed simultaneously with the principal I-918 petition or separately afterward.
What if my derivative family member has a criminal record or prior deportation? ▼
A derivative with a criminal history, fraud finding, or prior removal order may still qualify, but they must file Form I-192, Application for Advance Permission to Enter as a Nonimmigrant, to waive the ground of inadmissibility. USCIS evaluates waiver requests on a discretionary basis, considering hardship to the principal U visa holder and the derivative's rehabilitation.
Can my derivative family members live outside the U.S. and still apply? ▼
Yes. Derivatives do not need to be in the United States when Supplement A is filed. If approved, they apply for U visas at a U.S. consulate abroad through consular processing, then enter the U.S. in U derivative status.
How long does USCIS take to process Form I-918 Supplement A? ▼
Processing time varies by service center and whether Supplement A was filed with the principal petition or separately. As of 2026, USCIS does not publish separate timelines for derivative petitions. Applicants should check case status online at uscis.gov or consult current processing estimates for Form I-918.
Can my derivative family members work in the U.S. while the petition is pending? ▼
Yes, if the principal applicant is on the U visa waiting list and the derivatives received deferred action. Derivatives in deferred action must file Form I-765 to obtain an employment authorization document, renewable annually. Once approved in U derivative status, work authorization is incident to status and no separate EAD is required.
What happens to my derivatives if I adjust to a green card before filing Supplement A for them? ▼
The U derivative filing path closes once you adjust to lawful permanent residence. After adjustment, you can only petition for qualifying family members through standard family-based immigrant petitions (Form I-130), which are subject to preference category backlogs and per-country caps. File derivatives before adjusting if keeping the family together is a priority.
