I am international student studying in US. I am about to graduate in my third year. I have done two experimental research but they are not too significant works. I want to do theoretical physics in the future and I really want to go to those top graduate programs in US. My GPA is around 3.7 and I am not sure which professor can provide me a strong letter of recommendation. My family is broken so I don't think I have the money to continue school. I tried to find some summer research, but most of them require US citizen or green card. I will try to apply for grad school in the end of this year, but I still have one year time after graduation which I don't know what I can do. Professor doing theoretical physics might consider me under qualify for their research since I don't have the chance to take QFT, GR yet. But I really want to do research in some theoretical aspects. What should I do in this case? Appreciated any advice!
