Last time Donald Trump was president, rumors of immigration raids terrorized the Oregon community where Gustavo Balderas was the school superintendent.

Word spread that immigration agents were going to try to enter schools. There was no truth to it, but school staff members had to find students who were avoiding school and coax them back to class.

“People just started ducking and hiding,” Balderas said.

Educators around the country are bracing for upheaval, whether or not the president-elect follows through on his pledge to deport millions of immigrants who are in the country illegally. Even if he only talks about it, children of immigrants will suffer, educators and legal observers said.

If “you constantly threaten people with the possibility of mass deportation, it really inhibits peoples’ ability to function in society and for their kids to get an education,” said Hiroshi Motomura, a professor at UCLA School of Law.

That fear already has started for many. “The kids are still coming to school, but they’re scared,” said Almudena Abeyta, superintendent of Chelsea Public Schools, a Boston suburb that’s long been a first stop for Central American immigrants coming to Massachusetts. Now Haitians are making the city home and sending their kids to school there.

“They’re asking: ‘Are we going to be deported?’” said Abeyta.

Many parents in her district grew up in countries where the federal government ran schools and may think it’s the same here. The day after the election, Abeyta sent a letter home assuring parents their children are welcome and safe, no matter who is president.

Immigration officials have avoided arresting parents or students at schools. Since 2011, U.S. Immigration and Customs Enforcement has operated under a policy that immigration agents should not arrest or conduct other enforcement actions near “sensitive locations,” including schools, hospitals and places of worship.
