Oh look:The U.S. Territorial Waters extend 12-Miles Out for the Conservatively Impaired. 13-Miles is outside U.S. Waters. One mile over is still one mile over.
CBP also may conduct warrantless inspections and searches at or near the border to enforce federal
immigration laws. Under INA provisions and DHS regulations, an immigration officer may inspect (e.g.,
examine passports) all persons entering the United States, potentially search aliens who appear to be
inadmissible, and collect aliens’ biometric data. Under INA § 287(a)(3) and DHS regulations, certain
designated officers (e.g., Border Patrol agents) may board “any vessel, railway car, aircraft, conveyance,
or vehicle” mostly within an area of 100 air miles from a U.S. “external boundary” to search for
unlawfully present aliens. The statute also authorizes designated officers “to have access to private lands,”
but not “dwellings” (including, in some jurisdictions, a home’s backyard and crawlspace) within 25 miles
from a U.S. external boundary for “patrolling the border” to prevent the unlawful entry of aliens.
CBP’s inspection and search powers are subject to Fourth Amendment constraints, but the degree of those
limits may turn on whether the search occurred at the border or further into the interior of the United
States.
