Final answer:
Section 1 of the I-9 form should be filled out by the employee on their first day of employment or before they begin work for pay. If an employee needs assistance due to language barriers or disabilities, a preparer/translator can fill out Section 1 and must complete the Preparer and/or Translator Certification area accordingly.
Step-by-step explanation:
The I-9 form is a critical document for employment in the United States, designed to verify the identity of workers and confirm their eligibility to work. According to the Immigration Reform and Control Act of 1986, Section 1 of the I-9 form should be completely filled out by the employee on the first day of their employment, but no later than the first day of work for pay. In cases where an employee is not able to complete the form on their own due to language barriers or disabilities, a preparer/translator can assist. When a preparer/translator is used, they must complete the Preparer and/or Translator Certification area of Section 1 at the same time the employee completes their portion of the form.
