I am a junior linguistics major at the University of Iowa in the United States. I want to study abroad for the fall '10 semester in the United Kingdom to bolster my credentials as a prospective Ph.D candidate at top American universities (Harvard, Yale, University of Chicago, etc.). My aim is to study Welsh or other Celtic languages.
Although I have been to the United Kingdom of several occasions, I profess to be woefully unacquainted with the upper education system there. Which universities or colleges should I be looking to that actively teach these languages? If you're not sure if they teach these languages, what places should I search for or research as mid-to-upper tier schools that would be welcoming to an international student? My school arranges these endeavors independently so there's no worry about actually being able to set this up (at the moment at least) and let's assume cost is not an obstacle.
Any help would be very much appreciated. No help is assumed .
