I will tell you that American History is a requirement for most 4 year degree programs in the U.S. — at least one semester — and it will be a lot easier for you if you have had a high school level version.

(BTW: What passport you hold has no bearing what-so-ever on this issue).

That being said, taking US history isn’t a bad idea, especially if you want to study in the US.

BUT I will say that for most American students, U.S. history is both a requirement in high school, and in college.

It might not be a requirement for you to graduate high school, OR to be admitted to some U.S. colleges as an International Student, but you’ll probably have to take it in college anyway.

And even if you don’t, it will be helpful, since many other classes (English, social studies, etc) will have references to U.S. history anyway.
