KANSAS CITY, Mo. -- As President Donald Trump cracks down on illegal immigration in the United States in his first week in office, one school district in the Kansas City metro is addressing the issue with local parents. In many districts, educators have sought to reassure immigrant parents that schools are safe places for their kids, despite the president’s campaign pledge to carry out mass deportations. The Trump administration announced Tuesday it would allow federal immigration agencies to make arrests at schools, churches and hospitals, ending a decades-old policy. FOX4 obtained a letter the Olathe School District sent to parents and staff on Wednesday stating, "our administration is fully aware of the executive action and is actively reviewing the changes to understand their implications for our district."

The letter goes on to say, "the safety and well-being of our students remain our highest priority. While these changes are being analyzed, our focus will continue to be on protecting and supporting our students and families. We appreciate your patience and understanding as we work through these developments." Immigrants across the country have been anxious about Trump’s pledge to deport millions of people. While fears of raids did not come to pass on the administration’s first day, rapid changes on immigration policy have left many confused and uncertain about their future. Several schools said they were fielding calls from worried parents about rumors that immigration agents would try to enter schools, but it was too early to tell whether large numbers of families are keeping their children home. The move Tuesday to clear the way for arrests at schools reverses guidance that restricted two federal agencies — Immigration and Customs Enforcement and Customs and Border Protection — from carrying out enforcement in sensitive locations. In a statement, the Department of Homeland Security said: “Criminals will no longer be able to hide in America’s schools and churches to avoid arrest.” Download the FOX4 News app on iPhone and Android An estimated 733,000 school-aged children are in the U.S. illegally, according to the Migration Policy Institute.
