US immigration law creates two distinct tracks for removing noncitizens. The inadmissibility track under 8 U.S.C. § 1182 applies to those "seeking admission" and uses grounds of inadmissibility — someone on this track can be detained without bond hearings and faces fewer judicial review options. The deportability track under 8 U.S.C. § 1227 applies to noncitizens who have already been "admitted" and provides stronger procedural protections, including the right to bond hearings before an immigration judge and judicial review of detention. The distinction between these two tracks is central to Blanche v. Lau.
