8 C.F.R. § 1240.1 : Aliens and Nationality — EXECUTIVE OFFICE FOR IMMIGRATION REVIEW, DEPARTMENT OF JUSTICE — IMMIGRATION REGULATIONS — PROCEEDINGS TO DETERMINE REMOVABILITY OF ALIENS IN THE UNITED STATES — REMOVAL PROCEEDINGS — Immigration judges

(a) Authority.
(1) In any removal proceeding pursuant to section 240 of the Act, the immigration judge shall have the authority to:
(i) Determine removability pursuant to section 240(a)(1) of the Act; to make decisions, including orders of removal as provided by section 240(c)(1)(A) of the Act;
(ii) To determine applications under sections 208, 212(a)(2)(F), 212(a)(6)(F)(ii), 212(a)(9)(B)(v), 212(d)(11), 212(d)(12), 212(g), 212(h), 212(i), 212(k), 237(a)(1)(E) (iii), 237(a)(1)(H), 237(a)(3)(C)(ii), 240A(a) and (b), 240B, 245, and 249 of the Act , section 202 of Pub. L. 105-100 of Pub. L. 105-277 , and former section 212(c) of the Act (as it existed prior to April 1, 1997);
(iii) To order withholding of removal pursuant to section 241(b)(3) of the Act and pursuant to the Convention Against Torture; and
(iv) To take any other action consistent with applicable law and regulations as may be appropriate.
(2) An immigration judge may certify his or her decision in any case under section 240 of the Act to the Board of Immigration Appeals when it involves an unusually complex or novel question of law or fact. Nothing contained in this part shall be construed to diminish the authority conferred on immigration judges under sections 101(b)(4) and 103 of the Act.
(b) Withdrawal and substitution of immigration judges. The immigration judge assigned to conduct the hearing shall at any time withdraw if he or she deems himself or herself disqualified. If an immigration judge becomes unavailable to complete his or her duties, another immigration judge may be assigned to complete the case. The new immigration judge shall familiarize himself or herself with the record in the case and shall state for the record that he or she has done so.
(c) Conduct of hearing. The immigration judge shall receive and consider material and relevant evidence, rule upon objections, and otherwise regulate the course of the hearing.
(d) Withdrawal of application for admission. An immigration judge may allow only an arriving alien to withdraw an application for admission. Once the issue of inadmissibility has been resolved, permission to withdraw an application for admission should ordinarily be granted only with the concurrence of the Service. An immigration judge shall not allow an alien to withdraw an application for admission unless the alien, in addition to demonstrating that he or she possesses both the intent and the means to depart immediately from the United States, establishes that factors directly relating to the issue of inadmissibility indicate that the granting of the withdrawal would be in the interest of justice. During the pendency of an appeal from the order of removal, permission to withdraw an application for admission must be obtained from the immigration judge or the Board.
