Does rejecting an undergraduate admission offer have any effect on my chances of postgraduate admission? I am currently an international undergraduate studying in the US. When I was in school, I applied to a few different universities, including some in the UK. Two universities in the UK accepted me and I ended up rejecting them both. I am a freshman but I am strongly considering applying to their graduate schools after I graduate here. I understand that GPA, recommendations etc are very important, but would the fact that I had previously applied and rejected an offer from their undergraduate schools have any effect, negative or positive, on my chances of admission to a postgraduate course? Have I burned any bridges?

I can post the names of the specific universities if it's relevant.
I have worked on admissions councils and I'm 99.9% certain the answer is no.  I doubt they'll even consider whether or not you had previously applied.  I'd be surprised if they even have a way of looking up that information.  The pile of applicants who reject is tossed away pretty quickly, time to move on.
