It is never easy to make a huge decision such as aliyah. Where your going to live is going to be based on what is best for your family. If your single then you will probably end up in Yershulayim. There is a great website out there called Janglo.net its a networking site, for jobs, furniture, apts. If you have children where you live is going to depend on the type of schools your looking for.
Speak to NBN/ also if you can make a pilot trip if you have children so that you can find the right type of school for them. Good Luck!!!
Nefesh B’Nefesh’s website is a great place to start if you are coming from the U.S. or England. They have lots of information about different communities, and lots of other topics. They also sponsor “Aliyah fairs” in different locations throughout the U.S. where you can get a lot of information in one place.
Once you are seriously considering the move, and have narrowed it down to a few areas, a pilot trip can also be very helpful.
Talking to people you know, who know you, who have “been there, done that” is also a great resource.
