An S Visa is a rare, temporary, non-immigrant visa for foreign nationals who assist U.S. law enforcement or government agencies in investigating and prosecuting criminal or terrorist activities. It allows eligible witnesses and informants to live in the United States for a limited period while they assist in an active case or investigation.
Two main types
- S-5 Visa: For witnesses or informants assisting law enforcement in criminal investigations or prosecutions.
- S-6 Visa: For those who help U.S. authorities in counterterrorism efforts.
Key elements of an S visa
- For witnesses and informants: The S Visa is intended for individuals who can provide critical information or testimony about criminal or terrorist organizations or activities.
- Law enforcement sponsorship required: A federal or state law enforcement agency must submit the application and agree to oversee the individual’s stay in the U.S.
- Annual limits: Only 200 S-5 Visas and 50 S-6 Visas are available each year, making them extremely limited.
- Length of stay: Typically valid for up to three years, depending on the length of the investigation or cooperation period.
- Path to permanent residency: After fulfilling their cooperation terms, visa holders may be eligible to apply for a Green Card if recommended by a law enforcement agency and approved by the U.S. Attorney General.
- Family members: Spouses, children, and parents of S Visa holders may be eligible to join them under derivative S Visas.
Why the S Visa matters
The S Visa allows U.S. law enforcement to work with key witnesses and informants who can provide valuable information in serious criminal or national security cases. It helps protect those cooperating with the government while ensuring critical investigations can move forward. Because the visa requires law enforcement sponsorship and strict compliance with conditions, guidance from an immigration attorney can be helpful for clarity, protection, and support throughout the process.
