At an ATC info night we were informed that foreign carriers were not issued the Sheed arrival because they stuffed it up in the past. "Only for the locals...." I saw a Korean heavy wobble out of the sky onto RWY34 MEL some years ago giving the Sheed a try.
This definitely isn't a blanket "foreign carrier" rule as United perform it basically every day when 34 is in use. Saw the 74 come around the corner like a fighter jet on Friday just gone
