Black non-American tourists who have traveled to the US... What are your experiences compared to your home country regarding race?

There are loads of posts on reddit about "...How does country X or Y perceive black people" or ".....Should I avoid country Z as a solo female black traveler". Often written by black Americans and very insightful, also for black non-Americans. But still, from an American perspective.

On the other side, I couldn't find any posts about how n-A black tourists perceive the US. What are your experiences in the way people treated you compared to your home country (for example Brazil/South-Africa/Sweden)? What are other things have you noticed?
