S. 678 (2001) 683 Opinion of the Court I A The post-removal-period detention statute is one of a related set of statutes and regulations that govern detention during and after removal proceedings. While removal proceedings are in progress, most aliens may be released on bond or paroled. 66 Stat. 204, as added and amended, 110 Stat. 3009–585, 8 U. S. C. §§ 1226(a)(2), (c) (1994 ed., Supp. V). After entry of a final removal order and during the 90-day removal period, however, aliens must be held in custody. § 1231(a)(2). Subsequently, as the post-removal-period statute provides, the Government “may” continue to detain an alien who still remains here or release that alien under supervision. § 1231(a)(6). Related Immigration and Naturalization Service (INS) regulations add that the INS District Director will initially review the alien’s records to decide whether further detention or release under supervision is warranted after the 90-day removal period expires. 8 CFR §§ 241.4(c)(1), (h), (k)(1)(i) (2001). If the decision is to detain, then an INS panel will review the matter further, at the expiration of a 3-month period or soon thereafter. § 241.4(k)(2)(ii). And the panel will decide, on the basis of records and a possible personal interview, between still further detention or release under supervision. § 241.4(i). In making this decision, the panel will consider, for example, the alien’s disciplinary record, criminal record, mental health reports, evidence of rehabilitation, history of flight, prior immigration history, and favorable factors such as family ties. § 241.4(f). To authorize release, the panel must find that the alien is not likely to be violent, to pose a threat to the community, to flee if released, or to violate the conditions of release. § 241.4(e). And the alien must demonstrate “to the satisfaction of the Attorney General” that he will pose no danger or risk of flight.
