The employer normally, by qatari law, would provide you with health insurance which is comprehensive but does not cover dental works. 34000QR is the going rate for western mechanical engineers (and this includes allowances already) but i wouldnt know in the oil and gas sector. That rate ,net of housing, is considered a good one. Housing is one of the costly expenses here. My husband suggests you try to negotiate your salary in Euro because of the fluctuating exchange rate where a high euro rate makes one lose some hundreds at month's end.

The pre-schools shouldn't be a problem if you reserve a place for your baby with ample time before.

Buona fortuna.
