This section is completed by the preparer/translator themselves. [](/assets/images/zendesk/33460293375764.jpg) ## Completing Supplement A Per [I-9 official instructions](https://www.uscis.gov/sites/default/files/document/forms/i-9instr.pdf) (page 3), an employee can have more than one person support them in completing section 1: > There is no limit to the number of preparers and/or translators an employee may use. Each preparer and/or translator must complete and sign a separate Certification area. Employers must ensure that they retain any additional pages with the employee's completed Form I-9. If the employee does not use a preparer or translator, employers are not required to provide or retain Supplement A. As noted in the latest publication of the [I-9 Handbook for Employers M-274,](https://www.uscis.gov/book/export/html/59502) there are additional requirements and considerations when using a preparer/interpreter : * *Preparers and/or translators may not enter a P.O. box in place of a physical address.* * *Employees who use a preparer and/or translator to complete the form must still sign or make their mark in the Signature Field in Section 1.* * *Employers may provide the employee additional supplement pages as needed and attach them to the employee’s completed form.* * *The certification must also be completed for certain minors and employees in special placement who require a representative, parent, or legal guardian to complete Section 1 for them.* ## Minors (Individuals under Age 18) When an employee is a minor (individuals under age 18) and is unable to present an identity document from List B of the List of Acceptable Documents, the minor’s parent or legal guardian can establish identity for the minor by completing Section 1 on minor’s behalf and completing a Preparer and/or Translator Certification block in Supplement A. In this scenario, the minor must then only present an employment authorization document from List C. (See section Section 4.2 of the [I-9 Handbook for Employers M-274)](https://www.uscis.gov/book/export/html/59502).
