Top 3 Types of Evidence That Can Strengthen Your U Visa Application in 2026

At Santamaria Law Firm, we understand that a strong U Visa application requires more than showing that a person was the victim of a crime. Under INA § 101(a)(15)(U) and 8 C.F.R. § 214.14, an applicant must establish that they suffered substantial physical or mental abuse as a result of qualifying criminal activity, possess credible information about the crime, were helpful or are likely to be helpful to law enforcement, and satisfy the applicable admissibility requirements. USCIS generally requires Form I-918, Petition for U Nonimmigrant Status, together with Form I-918, Supplement B, signed by an authorized certifying official. The petition should also include evidence explaining the criminal activity, the harm suffered, the applicant’s knowledge of the crime, and their cooperation with law enforcement. 

How Can Official Criminal-Case Records Strengthen a U Visa Application?

The first important category is official evidence connecting the applicant to qualifying criminal activity. Depending on the circumstances, this may include police reports, incident reports, charging documents, court records, protective orders, arrest records, prosecutor correspondence, emergency dispatch records, or other documents created by law enforcement or the court. These records can help establish what happened, when and where the incident occurred, the nature of the criminal activity, and the applicant’s relationship to the crime.

A police report is not always required to contain every detail necessary for USCIS approval. Reports may be incomplete, contain errors, or describe the incident using terminology that differs from the qualifying-crime categories under immigration law. For that reason, the application should explain how the facts relate to a qualifying criminal activity or a substantially similar offense. The official record should also be reviewed for consistency with the applicant’s personal declaration and the information provided in Form I-918, Supplement B. Differences in dates, locations, names, criminal classifications, or descriptions of the harm should be addressed rather than ignored. USCIS instructions explain that petitioners must submit evidence establishing that they were victims of qualifying criminal activity and may use Supplement B to help establish that requirement.  A law enforcement certification is essential, but it is not necessarily the only evidence USCIS may consider. A complete filing should provide a coherent explanation of the crime and include supporting records wherever they are reasonably available.

What Medical, Psychological, and Personal Evidence Can Demonstrate Substantial Abuse?

The second category is evidence of the physical or mental harm caused by the criminal activity. A U Visa applicant must generally demonstrate that the abuse was substantial. Evidence may include medical records, hospital or emergency-room records, treatment notes, psychological evaluations, counseling records, prescriptions, photographs of injuries, disability documentation, and statements from healthcare or mental-health professionals. Mental abuse can be significant even when the applicant has no visible physical injuries. A psychological evaluation may describe symptoms such as anxiety, depression, post-traumatic stress, sleep disturbance, fear, emotional distress, difficulty concentrating, or changes in daily functioning. The evaluation should, where medically appropriate, explain the connection between the symptoms and the qualifying criminal activity. A detailed personal declaration is also highly valuable. The declaration should describe the incident or pattern of conduct, the applicant’s immediate response, the physical and emotional consequences, changes in employment or education, effects on relationships, treatment received, and continuing concerns. It should be truthful, chronological, specific, and consistent with the available records.

USCIS evaluates substantial abuse by considering the totality of the circumstances, including the nature of the injury, the severity of the perpetrator’s conduct, the severity and duration of the harm, and the extent to which the incident affected the applicant’s physical or mental soundness. A series of acts may be considered together when evaluating the overall abuse.  The absence of medical treatment does not automatically defeat a U Visa claim. Some victims may have avoided treatment because of fear, financial limitations, immigration concerns, cultural barriers, lack of transportation, or the perpetrator’s control. In such cases, the applicant should explain the circumstances and provide other credible evidence, such as statements from family members, friends, coworkers, advocates, clergy, teachers, or other individuals who observed the effects of the abuse. The objective is not to exaggerate the harm. It is to document accurately how the criminal activity affected the applicant’s body, mind, safety, relationships, and ability to function.

How Can Evidence of Helpfulness and Cooperation Improve a U Visa Application?

The third category is evidence showing the applicant’s helpfulness to law enforcement. Form I-918, Supplement B, is the central document used by a certifying law enforcement agency to confirm that the applicant was a victim of qualifying criminal activity and was, is, or is likely to be helpful in the detection, investigation, or prosecution of that crime. The certification must be signed by an authorized official and is generally submitted with the U Visa petition. Additional evidence may include copies of police interviews, witness statements, 911 records, court appearance notices, prosecutor communications, victim-witness program records, subpoenas, evidence-submission receipts, or correspondence showing that the applicant responded to reasonable requests for assistance.

The applicant’s personal declaration should explain how they reported the crime, spoke with investigators, provided documents or information, identified the perpetrator when possible, attended court proceedings, or otherwise assisted the investigation or prosecution. If the applicant was unable to complete a particular step, the declaration should explain why. Helpfulness does not necessarily require that the perpetrator was arrested, prosecuted, convicted, or sentenced. A U Visa may still be possible where the applicant provided qualifying assistance but the case was closed, the perpetrator could not be located, or prosecution did not proceed. The critical issue is whether the applicant possessed relevant information and was helpful, is being helpful, or is likely to be helpful under the applicable legal standard. Applicants should also understand that cooperation may remain relevant after certification. An unreasonable refusal to provide assistance when reasonably requested may create problems, depending on the facts and the stage of the case. A signed Supplement B is necessary, but it does not guarantee approval. USCIS independently evaluates the complete petition, including the qualifying crime, substantial abuse, helpfulness, credibility, admissibility, and any waiver request.

What If Some Evidence Is Missing or the Criminal Case Was Closed?

Missing evidence does not automatically mean that a U Visa application is impossible. However, the applicant should explain why a particular document is unavailable and provide credible substitute evidence when possible. For example, if police records cannot be obtained, the applicant may provide a detailed declaration, court correspondence, statements from witnesses, medical records, protective-order documents, or evidence from a victim advocacy organization. If the criminal case was closed, the applicant may still be able to demonstrate that they reported the crime and cooperated with law enforcement. The evidence should be organized so that each document serves a clear purpose. A strong application generally connects the records to the legal requirements instead of submitting large quantities of unrelated material. The applicant should also review whether a Form I-192, Application for Advance Permission to Enter as a Nonimmigrant, or another waiver-related filing may be necessary to address inadmissibility concerns. Waiver eligibility is fact-specific and should be evaluated carefully before submission.
