20 CFR § 655.42 - Newspaper advertisements.
(a) The employer must place an advertisement (which must be in a language other than English, where the CO determines appropriate) on 2 separate days, which may be consecutive, one of which must be a Sunday (except as provided in paragraph (b) of this section), in a newspaper of general circulation serving the area of intended employment and appropriate to the occupation and the workers likely to apply for the job opportunity.
(b) If the job opportunity is located in a rural area that does not have a newspaper with a Sunday edition, the CO may direct the employer, in place of a Sunday edition, to advertise in the regularly published daily edition with the widest circulation in the area of intended employment.
(c) The newspaper advertisements must satisfy the requirements in § 655.41.
(d) The employer must maintain copies of newspaper pages (with date of publication and full copy of the advertisement), or tear sheets of the pages of the publication in which the advertisements appeared, or other proof of publication furnished by the newspaper containing the text of the printed advertisements and the dates of publication, consistent with the document retention requirements in § 655.56. If the advertisement was required to be placed in a language other than English, the employer must maintain a translation and retain it in accordance with § 655.56.
