but in no case greater than 100 air miles, as the maximum distance from 
an external boundary of the United States in which the authority 
described in paragraph (1)(C) may be exercised, if the Secretary

subparagraph (B).
    ``(B) In making the certifications described in subparagraph (A), 
the Secretary shall consider, as appropriate, land topography, 
confluence of arteries of transportation leading from external 
boundaries, density of population, possible inconvenience to the 
traveling public, types of conveyances used, reliable information as to 
movements of persons effecting illegal entry into the United States, 
effects on private property and quality of life for relevant 
communities and residents, consultations with affected State, local, 
and tribal governments, including the governor of any relevant State, 
and other factors that the Secretary considers appropriate.
    ``(C) A certification made under subparagraph (A) shall be valid 
for a period of 5 years and may be renewed for additional 5-year 
periods. If the Secretary finds at any time that circumstances no 
longer justify a certification, the Secretary shall terminate the 
certification.

on the Judiciary of the Senate, the Committee on Homeland Security and 
Governmental Affairs of the Senate, the Committee on the Judiciary of

        certification has been in effect, and the factors justifying 
        the certification.''.

Border Zone Reasonableness Restoration Act of 2018 This bill revises the border zone area in which Department of Homeland Security (DHS) officers may take certain immigration-related actions without a warrant. The Immigration and Nationality Act is amended to permit DHS officers to take the following actions without a warrant in order to patrol the border and prevent the illegal entry of persons:   board and search any vessel within U.S. territorial waters and any railway car, aircraft, conveyance, or vehicle within 25 air miles from an external U.S. boundary (a vehicle may not be stopped at a fixed checkpoint beyond 10 air miles from such boundary without reasonable suspicion that an occupant is illegally in the United States); and  access private lands, but not dwellings, within 10 air miles from such boundary.   DHS may establish, and shall certify to Congress, that: (1) a distance of up to 100 air miles is required in a sector for conveyance searches, and (2) a distance of up to 25 air miles is required in a sector for private land access. In making such certifications DHS shall consider reasons such as land topography, transportation, or consultations with state, local, and tribal governments.
