28 C.F.R. § 1.1
A person seeking executive clemency by pardon, reprieve, commutation of sentence, or remission of fine shall execute a formal petition. The petition shall be addressed to the President of the United States and shall be submitted to the Pardon Attorney, Department of Justice, Washington, DC 20530, except for petitions relating to military offenses. Petitions and other required forms may be obtained from the Pardon Attorney. Petition forms for commutation of sentence also may be obtained from the wardens of federal penal institutions. A petitioner applying for executive clemency with respect to military offenses should submit his or her petition directly to the Secretary of the military department that had original jurisdiction over the court-martial trial and conviction of the petitioner. In such a case, a form furnished by the Pardon Attorney may be used but should be modified to meet the needs of the particular case. Each petition for executive clemency should include the information required in the form prescribed by the Attorney General.
