Some of the undocumented immigrant survivors of the Pulse tragedy are in legal limbo. They’re trying to get a visa under a special category- for victims of certain crimes who assist law enforcement in investigations. Immigration Attorney Raquel Santiago is helping out one person from Honduras and another from Guatemala.

They’re trying to get a U-visa. It provides legal status for at least four years and gives people a work permit. The U.S. has a cap of 10,000 U-visas per year. Santiago said there are more applicants than available visas, creating long wait times. She said the estimated time for an applicant to get a decision is more than 18 months.

A year after the Pulse shooting, these two survivors are still waiting.

After three years of having this visa approved, a person can apply for a green card, or legal permanent residency. That’s if they meet certain requirements including keeping a clean criminal record.

” A U-visa is a door that you can cross in order to have, eventually a green card or U.S. citizenship,” said Santiago.
