They are a group of progressive Jewish organizations and congregations, and they are coming to the defense of Rumeysa Ozturk, a Muslim graduate student at Tufts, who faces deportation after she helped write an essay critical of Israel.

The coalition includes synagogues in places like West Newton, Mass., San Francisco and the Upper West Side of New York, along with J-Street, a pro-Israel advocacy group. On Thursday, they filed a brief in federal court in Burlington, Vt., objecting to the tactics the government was using against Ms. Ozturk in the name of combating antisemitism.

In the brief, the groups argued she should be released from the Louisiana immigration detention center where she has been held for over two weeks, after masked immigration agents surrounded and arrested her on a street near her home in Somerville, Mass.

“Jewish people came to America to escape generations of similar predations,” the brief says. “Yet the images of Ozturk’s arrest in twenty-first century Massachusetts evoke the oppressive tactics employed by the authoritarian regimes that many ancestors of amici’s members left behind in Odessa, Kishinev, and Warsaw.”

There have been reports of almost 1,000 international students and scholars at universities across the country who have lost their legal status since mid-March, according to the Association of International Educators.

Anecdotally, the visas have typically been revoked with little or no notice and without telling the students what they might have done wrong. In some cases, students have committed legal infractions, like speeding or driving while drunk, according to universities and lawyers that are monitoring the revocations. But some have not. If the students do not leave voluntarily, they face deportation.
