It sounds that way. Almost as if it were the polar opposite in every way.

That isn't what I meant. I meant that people from other countries wouldn't have the same things available to them as the people originally from that country. They'd have to exchange their currency, possibly hire an interpreter, might not have firsthand experience with the culture...things like that.

And even then, there are laws regarding possession of certain kinds of items, particularly weapons. For example, one country may permit civilians to carry firearms, and another might not. And if a civilian from the former visits the latter, he wouldn't be permitted to bring his firearm with him.
