Hello,
I moved here with my daughter a year and a half ago and would like to share my opinions and experiences with you to give you a firsthand perspective. If you want to integrate into this society then you should first find a place to live and you'll then be required to enroll your child in the local public school within that district. Things are very different here, not like what you're accustomed to. My daughter has been here, going to a public school for 8 months, and is now tri-lingual and has many friends. The schools are very small and all about equal (within reason) in providing a quality education and environment. They have a two hour lunch break in which many children walk home for lunch. (and yes, this area is very safe as all children walk to and from to school) Those who do stay at school for lunch get a gourmet meal for 3chf/day. They have a 4 day school week and after school programs. They all learn to swim, ski, and go camping and such. Wedensdays they have no school as this time is used for Dr.'s appointments but this may be changed soon, there is a vote planned. The early years are focused on languages (3 required) and social skills (my daughter's class goes to a restaurant for lunch to practice for the real world). It's not uncommon to see kids on the tram or buses getting around.
So, don't worry so much about the kids fitting in, work on integrating yourself and they will follow. The housing issue is quite a problem but if you throw enough money at it then you'll find something fairly quickly. Expect to pay twice as much as you want for half the space you need. I live in the Old City and am quite happy here as I hardly use my car. The city is very easy to get around: my door to the airport in 11 min. by tram/ train if you time it right!!!
All in all, Geneva is a great palce to live and raise a family.(but I'm sure you knew that)
About Geneva, Switzerland
Set along the River Rhone with the majestic Alps towering in the background, Geneva commands attention. As the home of the International Red Cross and former home of the League of Nations, the city also possesses a multicultural flair. Indeed, French culture and language are still predominating aspects of Geneva today. Geneva has always exuded a chic superiority. The beautifully manicured city abounds with graceful mansions, gull-laden lakes, cosmopolitan stores, and elite restaurants. The heart of the city is called the rive gauche, which includes the charming old town area. Visitors should take time to stroll the quaint boutiques and galleries along the cobblestone Grand Rue. Also check out the Cathedrale St. Pierre, where John Calvin preached; the Reformation Monument, dedicated to leaders of the Protestant Reformation; and the Jet d'Eau, the highest fountain in Europe.
