I am an International Student, rising Junior and wondering about transfer.

I am currently an International Student in undergraduate physics program of liberal arts school in Minnesota with a GPA. I liked how almost every physics class has a lab with it separately from the regular class schedule during the week. I am currently thinking of transferring to a bigger university because I was having an expectation that I might have more challenges (in competition), if I were to go one. I have very limited range of schools I can pick due to financial restraints. I can pick four out of the followings: Columbia University, UPenn, Tuft, and Brown. Which school has a class system where the class schedule and the lab schedules are quite balanced and guarantees on-hand experience, assuming that I have enough GPA to go to one?

Each of those universities should have degree requirements for the major, and course schedules for each semester posted on line. Spend a bit of time at each website and hunt down that information.
