I asked a question over on the Workplace Stack Exchange after being asked to bring either a passport, birth certificate, or naturalization document with me to a job interview. From what I gathered from the answers, the employer either needs to verify my identity/citizenship to comply with regulations for the facility, or HR is expecting that I fill out an I9 to avoid wasting time on those that can't complete the form acceptably.
The interview is not until next week so I do not know the answer, yet, but I am interested in the possible legal question. From what I have read, it is illegal for an employer to request an I9 form be filled out prior to extending an employment offer. I am not a lawyer, so I am unsure as to whether or not this is true, or enforced. Would this scenario in fact be illegal?
