Something just hit me about certain laws in both the wizarding and muggle world.

In the muggle world, every single U.S. Embassy around the world that is stationed in whichever cities part of countries outside of the United States, whether in South America, Central America, Europe, Africa, Asia, or Oceania, they have NO jurisdiction and authority while on American soil and are subjected to America's laws.

I believe that this should also apply to MACUSA as well by extension. For one thing, there could very well be magically hidden wizarding offices inside the Embassies hosted in the cities of whichever countries they are based in, where some American wizards and/or witches work and live there, presumably serving as a liaison or representative, which means that not only are the international muggle governments subjected to America's laws in the muggle world, but also the magical governments in whichever countries are also subjected to wizarding America's laws.

And if foreign wizards and/or witches wished to apply for dual or multiple citizenships for their home countries and America, they'd have to go through something similar with the wizarding office just the same as muggles do.

I can also see that every single U.S. Embassy would be incorporated with and placed under very powerful, customized, everlasting, permanent, and inexhaustible protective barriers, enchantments, and security against dark forces, corrupt/dishonest politicians, and other despots of wizarding origin, irrespective of their magical blood statuses, preventing them entering the facilities and trespassing.
