Under what authority can a Canadian vessel be boarded and searched for aliens once it is in U.S. territory?

  1. INA 235

  2. INA 287

  3. INA 245

  4. INA 199

The correct answer is: INA 235

The authority to board and search a Canadian vessel for aliens once it is in U.S. territory falls under INA 235. This section of the Immigration and Nationality Act provides Immigration Officers the permission to inspect individuals seeking admission into the United States, which extends to any vehicles, vessels, or aircraft carrying such individuals. When it comes to vessels, this authority allows officers to conduct inspections to ensure compliance with immigration laws. INA 235 specifically addresses the control and procedure for inspection of individuals at ports of entry, and it is particularly relevant in situations where foreign vessels, such as those registered in Canada, enter U.S. territorial waters. The other options relate to different aspects of immigration enforcement but do not specifically grant the authority for the boarding and searching of vessels in this context.
