Every U.S. employer has to confirm that its workers are authorized to work — but federal law also protects employees and applicants from being singled out or mistreated over immigration status. Knowing where the line sits helps you spot when an employer has crossed it.
What employers are required to do
Under the Immigration Reform and Control Act (IRCA), employers must verify the identity and work authorization of everyone they hire by completing Form I-9, and some employers also use E-Verify. So an employer can require proof that you are authorized to work. That much is not discrimination — it is the law.
What employers may not do
IRCA’s anti-discrimination provision (often enforced by the Department of Justice’s Immigrant and Employee Rights section) prohibits several things:
Citizenship-status discrimination — refusing to hire someone because they are not a U.S. citizen, when they are otherwise authorized to work (with only narrow exceptions where a law or contract requires citizenship).
National-origin discrimination — treating someone worse because of where they or their family come from, their accent, or how they look or sound.
Document abuse — demanding more or specific documents than the law requires, rejecting valid documents, or specifying which acceptable documents you must show. On the I-9, you choose which valid documents to present from the list of acceptable ones.
Retaliation — punishing someone for asserting these rights or filing a complaint.
Timing and “are you a citizen?” questions
Employers generally verify work authorization after making a job offer, through the I-9. An employer that quizzes applicants about their citizenship or national origin, or treats non-citizens differently during hiring, may be crossing into prohibited discrimination. It is lawful to ask whether you are authorized to work in the U.S. and whether you will need sponsorship; it is different to reject you simply for not being a citizen when you are authorized.
If you think your rights were violated
Document what happened, keep copies of what you were asked for, and consider filing a complaint with the appropriate federal office or the EEOC (for national-origin discrimination). Deadlines apply, so act promptly.

The law behind your rights at work
Federal anti-discrimination laws are enforced by the EEOC, which has strict charge-filing deadlines.
Your state and city matter. Federal law is the floor — many states and cities require higher pay, more leave, and broader protections. Always check your state’s rules (and any local ordinances) in addition to the federal laws above. This is general legal information, not legal advice.
Frequently asked questions
Can an employer ask if I’m authorized to work in the U.S.?
Yes. Employers must verify work authorization through Form I-9 (and sometimes E-Verify), so they can ask whether you are authorized to work and whether you will need sponsorship. That is required by law, not discrimination.
Can an employer demand specific documents to prove I can work?
No. Demanding more or specific documents than the I-9 requires, rejecting valid documents, or telling you which acceptable documents to show is “document abuse” and is prohibited. You choose which valid documents to present from the acceptable list.
Can I be refused a job for not being a U.S. citizen?
Generally no. Refusing to hire an otherwise-authorized worker because they are not a citizen is citizenship-status discrimination, except in narrow cases where a law or contract requires citizenship. National-origin discrimination is also prohibited.
What can I do if an employer discriminated based on my status?
Document what happened, keep copies of what you were asked for, and file a complaint with the appropriate federal office or the EEOC for national-origin discrimination. Deadlines apply, so act promptly, and consider consulting an attorney.
