20 CFR § 655.434 - Amendments to an application.

(a) Increases in number of workers. The CW–1 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 CW–1 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 is wholly outside of the employer's control. All requests to increase the number of workers must be made in writing and will not be effective until approved by the CO. Upon acceptance of an amendment, the employer must promptly provide copies of any approved amendments to all U.S. workers recruited and hired under the original job offer.

(b) Minor changes to the period of employment. The CW–1 Application for Temporary Employment Certification may be amended at any time before the CO's certification determination to make minor changes (meaning a change of up to 14 calendar days) in the total period of employment, without requiring an additional recruitment period for U.S. workers. 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 is wholly outside of the employer's control. The CO will deny any request to change the period of employment where the total amended period of employment will exceed the maximum applicable duration permitted under § 655.420(g). Upon acceptance of an amendment, the employer must promptly provide copies of any approved amendments to all U.S. workers recruited and hired under the original job offer.

(c) Other minor amendments to the CW–1 Application for Temporary Employment Certification. The employer may request other minor amendments to the CW–1 Application for Temporary Employment Certification at any time before the CO's certification determination is issued. In considering whether to approve the request, the CO will determine whether the proposed amendment(s) are sufficiently justified and must take into account the effect of the changes on the underlying labor market test for the job opportunity. All requests for minor changes must be made in writing and will not be effective until approved by the CO. Upon acceptance of an amendment, the employer must promptly provide copies of any approved amendments to all U.S. workers recruited and hired under the original job offer.

(d) Amendments after certification are not permitted. After the CO has made a determination to certify the CW–1 Application for Temporary Employment Certification, the employer may no longer request amendments.
