Safetyness for girl to be alone in Al Khobar

Hi,

My husband has got a commisioning engineer job in Al khobar in electrical field and we are planning to move there, currently we are in India. I am expecting a baby in 15-20 days. I was born and brought up in Jeddah, Saudi until I completed my 12th std so I know the culture over there and I am used to it.

The info I need is my husband's job involves working in power plants in other cities so I would have to stay alone for a week or two with a new born at home. How safe is it for me to stay alone? And can I go alone or shopping or to the hospital when my hubby is not there in town?

I am currently a software engineer and in Saudi I dont think there are jobs for IT field. If at all I need to take a teaching job, B.Ed. will be necessary for teaching job I guess, so will it be possible for me to do corress courses in Al Khobar?

If we take up the offer I am planning to move after my baby completes 3 months. How long will it take to get a famly visa and how much wud it cost?

How much does a decent 1 bedroom flat cost for rent?
