Immigration officers in Massachusetts are again directed to arrest undocumented immigrants who show up for appointments at government offices in an abrupt reversal of a February order that ended that practice, according to court files.

The policy change came to light in an affidavit filed by Rebecca Adducci, who on June 7 took over as interim director of US Immigration and Customs Enforcement's Boston field office. Monday is her first day working in Boston, according to the affidavit.

Adducci said that under her leadership the Boston ICE office will strictly follow President Trump's Jan. 25 executive order on immigration. This means that any undocumented immigrant - not specifically violent criminals or others deemed as dangerous - can be held in detention.

This policy is the subject of a federal lawsuit, filed by the ACLU on behalf of immigrant couples.

In January at least seven people in Massachusetts and Rhode Island were arrested during or following their appointments with the United States Citizenship and Immigration Services. Lucimar de Souza, Lilian Calderon, and others were arrested outside CIS offices where they were securing their legal status after marrying US citizens.

In February Thomas Brophy, the then acting director of Boston's ICE field office, ordered officers to stop arresting undocumented immigrants visiting federal offices hoping to secure their legal status, he told a federal court judge.

He told Judge Mark Wolf in May that he told the officers to focus on people that posed a threat to public safety, rather than people without criminal records, like Calderon and de Souza.

Adducci will again change the policy and take a stricter approach. In her affidavit, she says that while cases involving people convicted of a crime, or who pose a threat to national security will continue to be prioritized.

"No classes or categories of removable aliens are exempt from enforcement, including detention," Adducci wrote in her affidavit.

Adducci's statement comes as people continue to raise questions about which Boston institutions are sharing information with ICE.

Boston Superintendent Tommy Chang announced he would resign on Friday, one day after a lawsuit was filed against Boston Public Schools, alleging the department shared information about a student that led to that student's deportation, according to CNN.

At a City Council meeting last week residents, organized by the Muslim Justice League, accused Boston police of sharing information from its database with ICE agents, despite promising not to collaborate with federal immigration authorities.
