The move, which could expose unregistered migrants to criminal prosecution, represents a drastic escalation of the administration’s efforts to push millions of immigrants to leave on their own.

Under new rules, all undocumented individuals who are 14 or older will need to register with the federal government and provide their fingerprints.

But lawyers and immigrant advocates warned that the administration’s plan was on shaky legal ground and that some immigrants may be afraid to comply.

The Trump administration is creating a registry of immigrants who are in the country without documents. Those who fail to register could face criminal or financial penalties. Immigration attorney Allen Orr joins José Díaz-Balart to explain more.

US President Donald Trump's administration has said it will create a national register for undocumented migrants, with those failing to sign up possibly facing criminal prosecution. The Department of Homeland Security (DHS) announced on Tuesday that any undocumented migrants above the age of 14 must provide the US government an address and their fingerprints.
