Hi, I am an -international- senior student in Electrical Engineering. I will apply for PhD programs in US for 2014 Fall semester, most probably in signal processing field. I am new to the application staff and I have a -really silly- question in my mind that somehow prevents me to search grad schools: Before making applications, do I need to determine all the labs in all schools that I want to get in and state all these in my applications? Or is it enough to determine and state just the schools I want? Finding labs is very hard for me because I have very little time and I cannot decide which one is better or more convenient for me right now. And things get worse as I investigate since I get lost easily when I try to look into the schools that deep. It would be nice for me to get an experienced hand to calm down
