Narrative:

A C680; checked on to frequency (very thick accent). I verified his mode C and verified his assigned altitude of 11000. I issued a 070 heading out of pvd VOR to intercept the runway 4R localizer. He said 'roger; zero seven zero'. Moments later I noticed his altitude out of 10000. I asked for an altitude verification and issued a climb. Then I pointed the aircraft out to the adjacent facilities who responded that there was no problem and point out approved. Continued with routine handling. Just a language barrier. Just a foreign pilot and language; although we use english as a common language in ATC; can be a barrier.
