What type of documentation should I obtain to ensure my nanny is legally able to be employed in the United States?
An employer may not knowingly engage an unauthorized alien for work, even under independent contract. As an employer, you must attest on an I-9 form to having seen prescribed documentation of any job applicant’s identity and authorization to work. Acceptable I-9 documents include: a U.S. passport, driver’s license, social security card, certificate of U.S. citizenship or naturalization, or an alien registration receipt card.
