[Harry Potter] how powerful are practitioners of brujería, Native American magic, voodoo, Santería, and the like? Do they have different abilities than European wizards? What's wizardry like in the United States and Latin America?

For example, are there gun-wielding Texas cowboy wizards? Are there Native American shapeshifters and mystics? Could sacrificial blood magic still exist in Mexico? What possibilities do exist?

I recall there is a little bit of insight into different countries in Goblet of Fire when they are walking around the campsite before the World Cup. We definitely know that there are magic users abroad (The Salem Witches' Institute as an example). Presumably other countries outside of Europe are able to enchant broomsticks to be able to complete, and there is some allusion to enchanted flying carpets (so perhaps middle eastern magic on par with Europe). 

Wands may also not be the only tool used by magic users worldwide (though certainly popular in Europe). Magic can be done without one, and objects can be imbued with magic (I guess Hagrid's umbrella could be a bad example off hand). Perhaps magical items (unicorn hair, dragon heartstrings...) could be placed in other ritually used items such as staves.

Also in Goblet of Fire, one of the dragons is described as a Chinese Fireball, which presumably means there are dragons as widespread as the far east, necessitating some sort of magic users to keep them hidden (though perhaps not so will given their depiction readily in the culture).
