(a) Increases in number of workers. The Application for Temporary Employment Certification may be amended at any time before the CO's certification determination to increase the number of workers requested in the initial Application for Temporary Employment Certification by not more than 20 percent (50 percent for employers requesting less than 10 workers) 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 employer demonstrates that the need for additional workers could not have been foreseen, and the crops or commodities will be in jeopardy prior to the expiration of an additional recruitment period. All requests for increasing the number of workers must be made in writing.

(b) Minor changes to the period of employment. The Application for Temporary Employment Certification may be amended to make minor changes in the total period of employment before the CO issues a final determination. Changes will not be effective until submitted in writing and approved by the CO. 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 any change(s) would have on the adequacy of the underlying test of the domestic labor market for the job opportunity. An employer must demonstrate that the change to the period of employment could not have been foreseen, and the crops or commodities will be in jeopardy prior to the expiration of an additional recruitment period. Upon acceptance of an amendment, the CO will submit to the SWA any necessary modification to the job order.
