Is it common for international students to get to do summer physics REU's in the US? I am a 3rd year undergrad in Spain, although I am a legal resident of the US if that helps (no need for a visa or anything to that avail). I can get letters of recommendation from 2-3 professors one of which is in my area of interest. I would like to do something in astrophysics but I'm open to other areas as well. Do I have any chance of getting into a REU or do students studying abroad take a back seat to applicants with letters of recommendation from US professors?
