It depends. From the employer's insurer's perspective, they want this to sound simple: it was "just" harassment, you waited too long, there was no police case, and immigration relief is off the table.

That version is often too neat.

In reality, there is no fixed statutory deadline to file a U visa petition with USCIS on Form I-918. Waiting months or even years does not automatically kill the case. What matters is whether what happened qualifies as a listed crime, whether you suffered substantial mental or physical abuse, and whether a police, prosecutor, judge, or other authorized agency will sign the required Form I-918 Supplement B certification.

A bad boss, wrongful firing, or everyday workplace harassment by itself is not enough for a U visa. But some job-site situations do qualify if the facts fit crimes like:

• Trafficking
• Involuntary servitude
• Peonage
• Felonious assault
• Extortion
• Witness tampering
• Obstruction of justice

In Boston, possible certifying agencies can include the Boston Police Department, the Suffolk County District Attorney's Office, or another agency that investigated the crime. In some labor-related cases, a certifying agency may be tied to the investigation, not the firing itself.

The practical problem with waiting is evidence. Texts disappear, coworkers move on, memories soften around the edges, and agencies are less eager to certify old cases unless there is a solid paper trail.

If you already reported the abuse, cooperated, or are still willing to help, you may still have a path. If you never reported it, that makes things harder, but not always impossible if there is another official record.

Also, a U visa is capped at 10,000 principal approvals per year, so even strong cases often wait a long time. A bona fide determination can still lead to deferred action and a work permit before final approval.
