Narrative:

Aircraft received multiple changes to clearance and ended up off the arrival due to ATC vectors. Aircraft ended up left of approach corridor on the RNAV arrival; crew thought they were on course but ATC issued corrective vectors for arrival. Aircraft was cleared direct to outer marker and executed approach without incident. Landing and taxi in were uneventful.language is a continuous threat in mexican airspace. Their command of english is virtually nonexistent and they regularly use spanish in communication with aircraft. In addition; they at times issue clearances that are not able to be followed and then are upset when the aircraft are unable to comply with these clearances. This inability to follow clearances has everything to do with aircraft performance. On numerous occasions I have brought these issues up to our company and every time I am told nothing can be done. These communications come from our management personnel who never fly.
