I do not know of any place that has an absolute requirement for 3 or 4 years of study. Yes, they might prefer it, but that is a different thing. Provided the rest of your application is solid, fitting only 2 years of foreign language into your schedule will not be the thing that keeps you from being admitted. The real question is just exactly how good the rest of your application is.
What do you want to study in college? How much can your family afford to pay? Have you run the Net Price Calculators at the websites of the places currently on your list? Those are issues you need to sort out too.
