Title 8 › CHAPTER 12 — IMMIGRATION AND NATIONALITY › SUBCHAPTER II — IMMIGRATION › Part IX — Miscellaneous › § 1357
Immigration officers can question anyone they think might be an immigrant about their right to be in the United States. Without a warrant, they can arrest someone seen trying to enter illegally, or arrest someone in the country if they believe the person is here illegally and might escape before a warrant can be got. They can also arrest for felonies tied to immigration laws if they believe a felony was committed and the person might flee, and they can arrest for any U.S. offense if it happens in their view while they are doing immigration work. Under rules from the Attorney General, officers may carry guns and serve warrants and subpoenas. They may board and search ships in U.S. waters and search vehicles, trains, and planes near borders, and go onto private land (but not into homes) up to 25 miles from an external boundary to patrol for illegal entry. The authority to make certain felony arrests (when the officer has reasonable grounds but did not see the crime) only starts after the Attorney General publishes final rules that (i) list which officers can use force, including deadly force, and when, (ii) set enforcement standards, (iii) require officers to be certified after training that covers those arrests and standards, and (iv) create a fast internal review process for violations that protects confidentiality. Designated officers can give oaths and collect evidence about a person’s right to enter or stay; lying under oath is a crime. Officers may search, without a warrant, a person and their belongings if the person is seeking entry and there is reasonable cause to deny admission. If someone is arrested for a drug crime and a law officer suspects they are not lawfully here, the officer can ask immigration to decide quickly whether to issue a detainer (a request to hold the person); if immigration issues it and the person is not otherwise held, the Attorney General must promptly take custody. Officers may not enter farms or outdoor agricultural land to question someone about immigration status without the owner’s permission or a valid warrant (except the border patrol rules above). The government must fingerprint and photograph any alien 14 or older who has removal proceedings, and share those images with law enforcement on request. The Attorney General may sign written agreements letting state or local officers carry out certain immigration tasks if they are trained, follow federal law, and work under federal supervision. An immigrant child who was abused, neglected, or abandoned and fits special juvenile rules cannot be forced to contact the alleged abuser while applying for special immigrant juvenile status.
