I don't understand how you're taking 12 credits, that doesn't sound like a part time program. Anyways you'd have to check whatever school you're looking at to see what their minimum transfer credit hours are.
In general I've seen schools only refer to minimum/maximum credit hours for transfer applications not whether or not the person is a PT/FT. I'm pretty sure if you have the required credits that it doesn't matter what your school calls you.
For the OP; you need to apply around June so if you don't have the minimum credits on your transcript by then I don't think a school will consider you since they have to compare your GPA to other transfer applications. You could always transfer to a PT program at one of those schools, though I don't think it would be worth it if you are already in the market where you want to practice.
