Does it take away a lot of megabytes to add friend out of the U.S. on Facebook?

None at all

Any friends you list on Facebook, doesn't affect your storage at all. It might slightly affect the amount of time to load your Facebook page.

In country, out of country there is no difference, first it does not use any storage in your computer, but even if it did, where they are from does not effect storage of files
