A four year degree will open more doors and carry him further up the ladder, but it is going to be more work to achieve too. If he doesn't have a good aptitude for math and physics, it will be a tough goal to make. I saw quite a few struggle and fade out. Getting a good internship can help, but I had some friends that got too involved with work and never finished their degree because of it. Nothing wrong with a two year degree if he doesn't have the commitment to do four. (or five which a lot of people take)
