Is the salary offered to me to work in Dubai will be suffice for a family of two?

Your salary seem to be OK, but get it clearly on your Visa this amount as the Jebel Ali is a separate Industrial Area and the Visa will be issued from there only. it is 54 kms from Dubai which can be traveled by Car with in 45 minutes. and also normally all company provides pick up and drop. and many companies are working only 5 days a week. you will get accommodation in Karama, Burdubai, a single room accommodation for a monthly rent of 4000 to 5000 dhs. and your living expenses will be on average of Dhs.3000/- per month. medical are very costly. other weekend outing expenses and local commuting will be around Dhs.1500/- per month. so you will be spending an amount of Dhs.9,500 to Dhs.10,000/- still you can save around Dhs.4000/- to Dhs.4500/- a month which is equivalent to INR.50,000/- a month. all the very best and go ahead.
