§655.57 Request for determination based on nonavailability of U.S. workers.

(a) Standards for requests. If a temporary labor certification has been partially granted or denied, based on the CO's determination that qualified U.S. workers are available, and, on or after 21 calendar days before the date of need, some or all of those qualified U.S. workers are, in fact no longer available, the employer may request a new temporary labor certification determination from the CO. Prior to making a new determination the CO will promptly ascertain (which may be through the SWA or other sources of information on U.S. worker availability) whether specific qualified replacement U.S. workers are available or can be reasonably expected to be present at the employer's establishment within 72 hours from the date the employer's request was received. The CO will expeditiously, but in no case later than 72 hours after the time a complete request (including the signed statement included in paragraph (b) of this section) is received, make a determination on the request. An employer may appeal a denial of such a determination in accordance with procedures contained in §655.61.
