Key aspects of the U visa include:

Eligibility criteria: To qualify for a U visa, individuals must meet specific eligibility criteria, including being a victim of a qualifying crime that occurred in the United States or violated U.S. laws, suffering substantial physical or mental abuse as a result of the crime, having information about the crime, and being helpful, or likely to be helpful, to law enforcement agencies in the investigation or prosecution of the crime. Certain family members of the victim may also be eligible for derivative U visas.
Certification from law enforcement: As part of the application process, victims of qualifying crimes must obtain a certification from a law enforcement agency, prosecutor, or other designated authority confirming their cooperation in the investigation or prosecution of the crime. The certification serves as evidence of the victim’s assistance to law enforcement and is a critical component of the U visa application.
Duration of status: Once granted, a U visa provides temporary immigration relief and protection to the victim and their eligible family members for up to four years. U visa holders are eligible to apply for work authorization, allowing them to legally work in the United States during the period of their U visa status.
Path to permanent residency: U visa recipients may be eligible to apply for lawful permanent residency (green card) after three years of continuous presence in the United States and demonstrating continued cooperation with law enforcement in the investigation or prosecution of the crime. The process involves submitting an application to adjust status to lawful permanent resident (Form I-485), along with evidence of eligibility and documentation of ongoing cooperation with law enforcement.
Confidentiality and protection: The U visa program includes provisions to protect the confidentiality and safety of victims of qualifying crimes, including provisions for withholding information about the victim from the perpetrator, confidentiality of victim statements and testimony, and protection against retaliation or retribution from perpetrators or others involved in criminal activities.
