You'll find it quite easy to make friends once you get here. Education City has tons of kids, which is a huge plus. Since you have kids, your wife will want to check out Doha Expat Mums and Kids when she arrives (if not before) - there are tons of playgroups, tours around the city, coffee mornings, Mums Night Out, and family events. Visit the website at http://www.dohaexpatmumsandkids.com for more info - and welcome to Qatar!
