Federal immigration officers are asserting sweeping power to forcibly enter people’s homes without a judge’s warrant, according to an internal Immigration and Customs Enforcement memo obtained by The Associated Press, marking a sharp reversal of longstanding guidance meant to respect constitutional limits on government searches.

The memo authorizes ICE officers to use force to enter a residence based solely on a more narrow administrative warrant to arrest someone with a final order of removal, a move that advocates say collides with Fourth Amendment protections and upends years of advice given to immigrant communities.
