After news that federal immigration agents plan to raid cities across the country beginning Sunday and arrest people without documentation, Boston officials are assuring residents they will protect them.

The city is not aware of any immigration raids planned for Boston, according to Mayor Marty Walsh’s office.

“Placing fear in the hearts and homes of our immigrant families across the country is not an immigration plan, and it does not represent our American values,” Walsh said. “Unfortunately, fear has been a regular occurrence in the lives of our immigrant families since the start of this presidency. We need to put human dignity first and end practices that aim solely to separate the families that are an integral part of our community.”

The city is taking steps to make sure residents know their legal rights, according to the mayor’s office. Recent amendments to Boston’s Trust Act clarifies the role local law enforcement play within federal immigration laws. In Boston, local authorities are not to arrest someone solely based on their immigration detainer requests or status, unless otherwise ordered by a court, according to the mayor’s office.

The Center for Immigration Studies identifies Massachusetts as a sanctuary state, along with California, Colorado, Connecticut, Illinois, New Jersey, New Mexico, Oregon and Vermont.

The cities and towns of Amherst, Boston, Cambridge, Concord, Lawrence, Newton, Northampton and Somerville were also identified as “sanctuaries” by immigration officials, according to CIS data.

This means that police in these jurisdictions limit their cooperation with federal immigration authorities.

The mayor of Northampton declined to comment for this story. Officials in Amherst, Cambridge, Concord, Lawrence, Newton and Somerville did not return messages Thursday.
