Although the series focuses on Hogwarts, there are other wizarding schools throughout the world, according to Rowling. Obviously, you have Beauxbaton and Durmstrang, but Rowling also mentions at least one school in Brazil and one in the United States (reppin') called "Salem Witches Institute" Not as cool as going to Hogwarts I presume, but hey, beggars can't be choosers. And all the Americans who are reading this, just had their minds blown. (information for this was found here)
