The big providers (BlackRock, Vanguard and friends) typically have copies of their big funds domiciled in, at least, the US and Ireland (or sometimes Luxembourg); the European versions are UCITS-compliant, and often offered in an accumulating variant (not tax efficient in the US, but it is in some European counties), but otherwise basically the same thing.
