Which option reflects a valid stop for an administrative arrest under INA 287?

The option that reflects a valid stop for an administrative arrest under INA 287 is based on the language and provisions of that particular section of the Immigration and Nationality Act. INA 287(a)(2) specifically grants immigration officers the authority to arrest any alien who is in the United States in violation of the immigration laws. This provision allows for such arrests to be made without a warrant if the officer has probable cause to believe the individual is removable under the immigration laws.

The fundamental aspect of INA 287(a)(2) is its focus on the authority of officers to operate in a range of contexts to enforce immigration laws effectively. This includes the ability to conduct stops based on recognizable criteria that suggest an individual may be violating immigration statutes.

Other sections mentioned may not provide the same scope for administrative arrest or might relate to different powers or procedural aspects that do not directly address the authority to detain individuals facing immigration violations. Thus, the selection of INA 287(a)(2) underscores the specific provision that empowers officers to conduct valid stops for administrative arrests in accordance with the established immigration laws.
