Hi guys,

I'm kind of in a situation where I should make a decision and in this regard, I need your comments/suggestions. I do not want to be very elaborative and bore you people with too many words, so here are a few key points about me and some questions that I have:

1) International student admitted as a full time student to top 60 physics and astronomy PhD programs.

2) Research interests in quantum gravity, QFTs, Quantum Cosmology.

3) Upon talking to professors here, I realized there isn't anyone that I'm particularly interested to work with. The ones I'm interested in don't take students or are not having funding.

4) By the time I get my masters degree, I would have taken graduate courses in Classical Mechanics, Quantum mechanics, Classical Electrodynamics, Statistical Mechanics, Mathematical Methods in Physics, Differential Geometry and General Relativity, Introduction to Group Theory.

Should I opt out from this program with a masters degree and re-apply again? What are the chances of getting into better places than I'm in now? I'm looking for schools in US and Canada, but wouldn't mind Europe either.

Would there be any visa problem as I'm an international student?

Thanks in advance!
