Rubio's news comes one day after State Department cables revealed foreign visa interviews had been put on hold for new guidance.
A Rubio cable sent Tuesday ordered pauses of U.S. Embassy and consulate interviews for student visa applications.
"Effective immediately, in preparation for an expansion of required social media screening and vetting, consular sections should not add any additional student or exchange visitor (F, M, and J) visa appointment capacity until further guidance is issued septel, which we anticipate in the coming days," the cable read, according to Politico.
"Septel" is the State Department term for future guidance to come. That guidance appears to have been the visa restriction policy Rubio just announced.
