I was injured at work and I do not have papers. Can I claim anything?

Three separate things are true here, and the one people give up on is usually the one that would have paid.

Safety is not conditional

You have the right to a safe workplace regardless of immigration status. That is the federal position, stated plainly by OSHA, and a complaint about an unsafe condition does not ask what your status is.

Wages are not conditional either

The Labor Department enforces wage and hour law without regard to whether a worker is documented or undocumented. Hours you worked are hours you are owed, including overtime, and that does not change because of how you were hired or how you were paid.

Workers' compensation is decided by your state

This is the part that varies. Workers' compensation is state law, and most states cover injured workers regardless of immigration status — but the rules, the deadlines and the exclusions differ, and a page like this cannot tell you which apply to you.

The authority is your state's workers' compensation board, which the state pages on this site point to. What is worth knowing before you get there is that the belief "I cannot claim because of my status" is, in most states, simply wrong — and it is the belief that ends most of these claims, not any actual decision.

If your employer threatens you

Retaliation for reporting an injury or an unsafe condition is unlawful, and that includes retaliation involving immigration enforcement. An employer who suddenly discovers a problem with your paperwork after you report an injury is producing evidence of retaliation, not solving a problem.

Write down what was said and when. Keep it somewhere that is not a work device.

What to do about the bills meanwhile

Do not let an emergency go untreated while this is unresolved. Emergency departments must stabilise you regardless of ability to pay, community health centres charge on a sliding scale and do not ask about status, and every state has Emergency Medicaid for people who meet the income rules but not the immigration ones.

If the injury turns out to be covered by workers' compensation, those bills move to the insurer — but that is worked out afterwards, and it is not a reason to wait.
