Does this sound familiar?
You were the victim of a serious crime in the United States, cooperated with the authorities, and you know the U Visa exists. But nobody resolves the first thing: who signs the certification, which office it goes to, what documents the package must include and how to request a copy of the case record. A misdirected or incomplete package costs weeks — and the signature, once obtained, is only valid for 6 months.

What we do not do
The signature: the person requests it and the agency decides at its discretion. States that set a deadline,…
Before requesting the U Visa there is a first step that decides everything: that the agency that investigated or prosecuted the crime signs the official certification (Supplement B). This solution prepares that complete package — the request letter, the form with your data already completed, your disclosure authorization, the case evidence and the state statutes — and tells you exactly which office to present it to. You present it; we help you follow up until the answer. With the signature in hand, the U Visa petition is a separate solution.

The package for the signature, piece by piece.
With this you know what the package contains and who does what — no call needed to understand it.
The right agency, in any state
The certification is requested where the crime happened: the district attorney of the county that prosecuted the case, the police or sheriff that took the report, or a judge on the case. We verify the office with three sources before the envelope goes out.
The request letter
We draft it with the case data — date, charges, case number, cooperation — and you sign it. It goes by certified mail with return receipt.
The form already completed
We complete the parts that belong to the person and to the agency, on the current edition of the form, and leave the official only what they certify.
The case evidence
We print the public court record, tell you where to request the police report copy, and cite the statute for each charge from the state legislature.
Follow-up until the answer
Preliminary call to the victim unit, follow-up cadence (days 5, 15, 30, 45 and 60) and escalation if they do not respond. Signing is at the agency's discretion.
And then, the U Visa
With the signed and valid certification (6 months) the "U Visa" solution is added, which builds the complete petition before the government.

This is for you if…
Victims of eligible crimes
You suffered a serious crime in the U.S., such as domestic violence, assault, kidnapping, extortion or sexual abuse.
You cooperated with the authorities
You reported it, there is a police report or a court case, and you helped or are willing to help.
You need the agency signature
You know there is no petition without the signed certification, and you do not know whom to ask or how.
You come from another office
A certification was already signed and expired, or the previous package never got an answer: we review what still serves and what must be requested again.
To request the certification, the agency reviews criteria similar to those USCIS establishes for the U Visa:
Primary source: USCIS — Victims of Criminal Activity: U Nonimmigrant Status ↗
Everything we prepare with you.
Search and validation of the certifying office: county, name, address and designated official, confirmed with the court record, the county's official site and a preliminary call
Signature request letter drafted with your case data, ready for you to sign
Certification form (Supplement B) in its current edition, with the person's and the agency's parts completed
Printout of the public court case record and guidance to request the police report copy
Statute for each charge, printed from the state legislature
Step-by-step delivery instructions (where it goes, how to send it and what to keep as proof) and the return-envelope checklist
Follow-up with the agency until the answer, and field-by-field review of the certification when it arrives, with its expiration date recorded
