An immigration court blocked the deportation of a Turkish Tufts University graduate student who was detained by immigration officials near her Massachusetts home, her attorneys said in court documents filed Monday. Rümeysa Öztürk’s attorneys said the immigration court found on Jan. 29 that the Department of Homeland Security hasn’t proved that Öztürk should be removed from the U.S. The immigration court also terminated Öztürk’s removal proceedings, the attorneys said in a letter to the 2nd U.S.
