I know this bit awkward, but seriously I am in need of some advice due to my strange situation. Last year I joined a graduate school at US which is ranked below 150 as I got only offer from this university and rejected from the rest of universities where I applied. I was not at all happy with the program due to various reasons. First of all I had already masters degree and I am an international student of around 35 years old. So, I didn't want to continue the course as I had to spend two years attending coursework, in the meanwhile try to clear masters qualifying exam and to grapple with qualifying exam for PhD in the next three years given to me to qualify these exams, before I actually start with my PhD research. They told me that my Masters degree from my country is not recognized, so I have to sit for the MS qualifying exam. Besides, none of the research( mostly experimental) taking place in the school excites me as my interest is in theoretical physics. Moreover, I found difficulty in adjusting to the environment as the university town is bit far away from the city and its mostly ghost town. Due to these various reasons, I eventually lost interest in the program and decided to drop out of the school. After spending a semester, I left the program and finally got back at my country and coincidentally I am able to join a PhD program in my country. However, research potential is very limited in this current university due to poor infrastructure and I don't have supervisors who can actually help me in my research interest. So, I am thinking of applying somewhere in Europe for next academic session for physics PhD, where I can start my PhD straight away without having to do coursework and complete possibly in around 3 or 4 years. My question is, how would I convince the admission committee at universities in Europe so that I can get a berth in their PhD program? Wouldn't they think that I am incompetent for their position as I dropped out of US graduate school? Is it necessary to mention that I spent a semester at US graduate school and backed out before even completing a year of the program? Will it be impossible for me to get into programs at Europe? I am truly sorry for this long write up and I am thanking you in advance for your sincere advice and suggestion.
