How can I move my family from the US to Europe for 4-5 years?

A little background: I spent age 4 in Taiwan, 6–8 in Munich Germany and age 9 in Rome. I have always looked back fondly at my time overseas and felt that it gave me a much more tolerant and open-eyed view of the world.

My children are 4 and 7 and my wife and I are exploring the possibility of moving to Europe for a few years to afford our children this same opportunity.

We are in a really great place as a family, we don’t own a home and have a lot of money saved. My wife is a brilliant educator and I have close to 15 years of high tech project management and architecture experience. We both have jobs now, but would give them up if we could somehow make this work. The downside is that we do have a close family network. We would have to leave our parents who we are used to seeing frequently. But with communications as they are now as opposed to when I was a child staying in touch is much easier.

Now the kicker is that when I moved as a child it was due to my father’s job. He was a contractor for the US military so we moved from base to base and it was all relatively easy. We do not have this luxury, we do not know anyone in Europe at all. We also do not speak any foreign language anywhere close to fluently.

My wife’s best friend lives in Australia and if moving to Europe is anywhere close to as difficult as it is to move to Australia this may not even be possible. She has been trying for 4 years to gain citizenship without success.

At the top of our list is the UK mostly because of no language barrier and we enjoy British history and culture. We are also considering Spain, France and Germany as well.

If you have any experience with something like this or have any comments we would really appreciate them. Especially about finding a good job.
