There is a sticky at top that can help you, it is in the early pages. Can't remember which post number, look around 15-20 for it.
However, it is really to your best advantage to contact the individual college you want to attend. Colleges are unique not only for the majors they offer, but the feel of the school is different.
I don't know where you live, but let's say you live in NC are you going to travel to Idaho, AZ or Oregon if they offer IS for OOS along with going to TX too? Is it realistic to place those schools on your list just because they offer IS?
I get you are exploring your options, but my advice to you is you know what schools you like and how far away you are willing to go, start with your choices and contact the bursar to find out if they do.
