The arrests will target more than 2,000 people and will take place in at least 10 US cities.
ICE had planned to arrest and deport families with court-ordered removals in 10 cities in late June, according to a senior immigration official.
"It starts on Sunday, and they're going to take people out and they're going to bring them back to their countries", the president said of the planned raids as he left the White House for a trip to Wisconsin and Ohio. Parents should update emergency contact forms at their childrens' schools, and memorize an emergency contact number in case an arrest is made, Lopez-McCarthy said.
Administrative warrants are not the same as a judicial criminal warrant, and lawyers say migrants have the right to refuse entry to a home if ICE only has an administrative warrant. "If the word gets out, it gets out".

"Those of us who have lived through dictatorships understand what it's like to live under constant fear, we understand what it means to be disappeared", said Democratic Rep. "It's a major operation", Trump told reporters before boarding Marine One on July 12.
Reporters who joined the tour saw immigrants, including children, lying on mats on the floor covered with thin aluminum blankets. He prodded Mexico to take steps to block migrants from crossing into the USA after threatening the country with tariffs on goods last month.
Trump is to meet with Guatemalan President Jimmy Morales at the White House on Monday for talks on immigration and security.
Alongside these worldwide efforts, Trump has sought to deter border crossings with highly publicized crackdowns in the United States. A month later, James Schwab, who worked for ICE's San Francisco division, resigned, stating he could no longer "bear the burden" of spreading lies perpetuated by the Trump administration. Some of the people being targeted have deportation orders because they failed to appear in court, according to the Times. "Resources are here for those who have received an order from immigration courts or have concerns about their status". And on Friday he confirmed that federal agents would conduct raids over the weekend.
