20 C.F.R. § 416.1429
If you are dissatisfied with one of the determinations or decisions listed in § 416.1430 , you may request a hearing. Subject to § 416.1456 , the Deputy Commissioner for Hearings Operations, or his or her delegate, will appoint an administrative law judge to conduct the hearing. If circumstances warrant, the Deputy Commissioner for Hearings Operations, or his or her delegate, may assign your case to another administrative law judge. In general, we will schedule you to appear by video teleconferencing or in person. When we determine whether you will appear by video teleconferencing or in person, we consider the factors described in § 416.1436 (c)(1)(i) through (iii) , and in the limited circumstances described in § 416.1436(c)(2) , we will schedule you to appear by telephone. You may submit new evidence (subject to the provisions of § 416.1435 ), examine the evidence used in making the determination or decision under review, and present and question witnesses. The administrative law judge who conducts the hearing may ask you questions. He or she will issue a decision based on the preponderance of the evidence in the hearing record. If you waive your right to appear at the hearing, the administrative law judge will make a decision based on the preponderance of the evidence that is in the file and, subject to the provisions of § 416.1435 , any new evidence that may have been submitted for consideration.
