Atlanta CNN  —  A judge on Friday issued a temporary restraining order in the case of more than 100 international students in the United States whose visas were revoked by the federal government court documents show. The order by US District Court Judge Victoria Calvert temporarily prevents the deportation of 133 foreign students from at least five countries who filed a lawsuit seeking to stop the revocation of visas to international students, the order, which is valid until May 2, says.
