Updates:

I just asked the HR people and they said that private health care is provided free of charge but I have to pay som co-pay for office visits.

Also they said the kids tuition are covered from KinderGarten to grade12.

But still I have no annual air line tickets for free !

Also they said I can buy a car and still get the 2190 rials per month transport allowance.

But I will try to negociate a basic salary increase maybe 12k or so.
