bajadj - yes, you can do the night in the USA under the UK authorities - but why do you want to?
Part of other courses/training- yeah, ok, maybe - from a finacial point of view only. As a stand alone qualification - absolutely pointless.
You don't (normally) learn to fly at night in the USA. You learn how to follow a GPS on a "heads down" cross country and you learn how to do circuits - probably at your base airfield.
There's a lot more to night flying than that.
