Mullin v. Al Otro Lado · ¶90

The United States-Mexico border is dotted with designated ports of entry. Over 20 ports of entry are designated as “Class A,” meaning they are designated to “‘process all aliens applying for admission into the United States.’” App. 193, 215. These ports abut the border and include vehicle lanes, pedestrian walkways, and an arrival hall, all staffed with Customs and Border Protection (CBP) officials. Where the Rio Grande marks the border between the two countries, arrival halls are generally at the north end of a bridge spanning the river (with the border marked by a plaque on the bridge near the river’s midpoint). At land portions of the border, the border is marked by turnstiles on the road leading to the arrival hall.
