655.34—Validity of temporary labor certifications.

(a) Validity period. A temporary labor certification is valid only for the period of time between the beginning and ending dates of employment, as certified by the OFLC Administrator on the Application for Temporary Employment Certification. The certification expires on the last day of authorized employment.
(b) Scope of validity. A temporary labor certification is valid only for the number of H-2B positions, the area of intended employment, the specific services or labor to be performed, and the employer specified on the certified Application for Temporary Employment Certification and may not be transferred from one employer to another.
(c) Amendments to applications. (1) Applications may be amended at any time, before the CO's certification determination, to increase the number of positions requested in the initial application by not more than 20 percent (50 percent for employers requesting less than 10 positions) without requiring an additional recruitment period for U.S. workers. Requests for increases above the percent prescribed, without additional recruitment, may be approved by the CO only when the request is submitted in writing, the need for additional workers could not have been reasonably foreseen, and the employer's services or products will be in jeopardy prior to the time that new H-2B workers could be secured.
(2) Applications may be amended to make minor changes in the period of employment, only when a written request is submitted to the CO and written approval obtained in advance. In considering whether to approve the request, the CO will review the reason(s) for the request, determine whether the reason(s) are on the whole justified, and take into account the effect(s) of a decision to approve on the adequacy of the underlying test of the domestic labor market for the job opportunity.
(3) Other amendments to the application, including elements of the job offer and the place of work, may be requested, in writing, and will be granted if the CO determines the proposed amendment(s) are justified and will have no significant effect upon the CO's ability to make the labor certification determination required under § 655.32.
(4) The CO may change the date of need to reflect an amended date when delays occur in the adjudication of the Application for Temporary Employment Certification, through no fault of the employer, and the certification would otherwise become valid after the initial date of need.
