Is it permissible to combine and shorten the Dhuhr and Asr prayers, and to break the fast in Ramadan, for a daily commute of 90 kilometers round trip for work, knowing that I am an expatriate resident?

The distance that permits a traveler to shorten and combine prayers is 16 parasangs (83 km) from the point of departure to the intended destination, excluding the return journey. Travel concessions are not permitted for those who stay in a locality for more than four days.
