If you moved to the US, I'd suggest being very wary of gun ownership. That can feel very empowering. And it's pretty cool in a lot of social circles, kinda required in a few, seen less favorably in many others...but, unless our culture wars turn into actual shooting wars, there are few places in the U.S. where both (1) foreign-born people settle by choice and (2) gun ownership is net plus for the safety of your self and your family. (And (2) is dependent on you not merely owning a gun, but being fairly experienced in securing/handling/using it, plus pretty savvy about if/when/how to use it.)
