Border Patrol agents have been instructed to begin releasing illegal migrants into the country without a notice to appear in court as officials prepare for the expected surge in immigrants crossing the southern border, according to documents exclusively obtained by the Daily Caller News Foundation.

Border Patrol Chief Raul Ortiz sent the instructions Wednesday, asking senior officials in the agency to begin the mass parole of illegal migrants ahead of the end of Title 42, a Trump-era expulsion policy, on May 11. The illegal immigrants will be “parole[d] with conditions,” meaning they are required to schedule a court date with Immigration and Customs Enforcement (ICE) or request service of a Notice to Appear (NTA), according to the instructions.

However, the paroled illegal migrants will be released without any tracking technology, meaning there is no way to supervise them after their release, according to NBC News.
