Can you join phi theta kappa at 2 different community colleges?

Like PBK, PTK is a national organization for which you are inducted THROUGH your college. In other words, you qualify for admission based upon your college records, but once you're in the society, you don't need to join again. Think of it like a marriage. You can get married in one state, and if you move to a different state, you don't need to get married again.
