(e) Required pre-filing recruitment. Except for labor certification applications involving college or university teachers selected pursuant to a competitive recruitment and selection process (§ 656.18), Schedule A occupations (§§ 656.5 and 656.15), and sheepherders (§ 656.16), an employer must attest to having conducted the following recruitment prior to filing the application:
(1) Professional occupations. If the application is for a professional occupation, the employer must conduct the recruitment steps within 6 months of filing the application for alien employment certification. The employer must maintain documentation of the recruitment and be prepared to submit this documentation in the event of an audit or in response to a request from the Certifying Officer prior to rendering a final determination.
(i) Mandatory steps. Two of the steps, a job order and two print advertisements, are mandatory for all applications involving professional occupations, except applications for college or university teachers selected in a competitive selection and recruitment process as provided in § 656.18. The mandatory recruitment steps must be conducted at least 30 days, but no more than 180 days, before the filing of the application.
(B) Advertisements in newspaper or professional journals.

Documentation of this step can be satisfied by providing a copy of the page in which the advertisement appeared.
(ii) Additional recruitment steps. The employer must select three additional recruitment steps from the alternatives listed in paragraphs (e)(1)(ii)(A)-(J) of this section. Only one of the additional steps may consist solely of activity that took place within 30 days of the filing of the application. None of the steps may have taken place more than 180 days prior to filing the application.
(2) Nonprofessional occupations. If the application is for a nonprofessional occupation, the employer must at a minimum, place a job order and two newspaper advertisements within 6 months of filing the application.
