NSA's mission, as outlined in Executive Order 12333 in 1981, is to collect information that constitutes "foreign intelligence or counterintelligence" while not "acquiring information concerning the domestic activities of United States persons".

Whether they abide by that is another matter.

Well, their operations are (intended to be) foreign... But that hasn't stopped them from selling drugs to American to raise money for their operations.

Also the NSA is a "signals intelligence" agency... Wouldn't the FBI be the local analog to the CIA? Or maybe the DHS?

Well, the problem with that is then you have to deal with the legalities of the USA. What you do instead is have the UK (and a couple other eyes, up to five or eighteen) do the spying on Americans, and in exchange, the Americans will spy on the UK. All perfectly extra-legal.
