An applicant who matched to an advanced position also may request a waiver if the applicant has elected to change specialties, provided the waiver is requested no later than the January 15 prior to the start of training. The applicant must request the waiver in writing and must send the request to the NRMP with a copy to the program to which the applicant matched. The NRMP will investigate the waiver request to determine whether or not the waiver shall be granted.
