"The CBP Home app gives aliens the option to leave now and self-deport, so they may still have the opportunity to return legally in the future and live the American dream," Homeland Security Sec. Kristi Noem said in a statement. "If they don't, we will find them, we will deport them, and they will never return."
CBP Home replaces the Biden-era app known as CBP One which allowed migrants at the U.S.-Mexico border to schedule an appointment to request entry into the United States at a legal port of entry.
The app from the Biden administration was heavily criticized by Republicans, who said it paved the way for huge numbers of migrants to enter the U.S. without being properly vetted.
Trump shut down the CBP One app hours after being sworn in on Jan. 20.
