According to this link, UMass is no longer admitting students from Iran into many of its STEM graduate programs. This would be a very big deal if the same thing happened with us — we have a large number of CS students from Iran. (Irvine also has a large emigré Persian population but here I'm referring to Iranian nationals.) Has anyone heard more about this or similar actions?
(I got this from http://crookedtimber.org/2015/02/13/u-mass-will-no-longer-admit-iranian-students-to-graduate-schools-of-engineering-and-natural-sciences/ but you're probably better off ignoring that link as it twists this into somehow being about demonstrating that academic supporters of Israel are hypocrites, a subject I'm not particularly interested in.)
Update: they have changed their minds and will accept Iranians after all: http://www.umass.edu/newsoffice/article/umass-amherst-will-accept-iranian-students
