Ozturk was one of four students who wrote an op-ed in the campus newspaper, The Tufts Daily, last year criticizing the university’s response to student activists demanding that Tufts “acknowledge the Palestinian genocide,” disclose its investments and divest from companies with ties to Israel.

A federal judge in Vermont had ordered immigration officials to return the Tufts doctoral student to his court by May 1.

The Turkish national's return will be delayed until at least May 6 to allow for a government appeal, a federal judge ruled Monday.
