Is it hard for a foreign school graduate to get in the University of California SanFo School of Medicine?

I'm just a new immigrant here at the US since 2009. I graduated Bachelor of Science in Nursing from the Philippines recently. And now, I'm planning to take Doctor of Medicine at the University of California San Francisco. Im really clueless about the steps that I need to take for me to study in this school. I badly want to pursue my doctoral career. I read in the different threads and discussions about SAT etc, Can anyone help me or give me helpful infos? I hope I qualify in this school. In fact, I did great in my BSN years. I graduated with flying colors. Thanks :)
