> Do you ever see US immigration politics talking about anything else than Mexico?
As a Californian: all the damn time. Mexico is the target of immigration debates because it's the U.S.'s immediate neighbor; most immigrants (legal or otherwise) from South and Central America either go through Mexico or take a boat.
North America differs from Europe only in the linear arrangement of nodes in a migration graph. In terms of origins, I reckon you're significantly downplaying the similarities.
