Most of the issues written about in this thread are true but are usually not long-term issues.
You eventually get used to the (usually nutty) way things are over here. Even the financial issues usually work out in the end.
You can survive with broken Hebrew too. Most Israelis actually find it cute and endearing – and having English as a mother tongue often gives you points in finding a job – especially in the high-tech sector.
But there are other points to take into consideration.
I have been living in EY for well over 20 years.
As the years went by, one by one, most of my friends found some reason to move back.
I slowly started realizing that most chutzniks are never fully able to shake the feeling of “outsider”.
This is even for those who seemingly “fit in”; speak Hebrew perfectly (even down to the hard “L”amed), are surviving financially and don’t have too much difficulty with the children – many chutznikim do (either because the child is too Israeli and can’t relate to their parents or is too chutznik and doesn’t fit in well).
Living day after day with this “outsider” feeling slowly wears you down.
This is not something you can test by coming here for a summer.
Because of this, I’ve started advising people who want to do aliya to have a very good reason to do so.
Once you live here for many years and your children become Israelis, it will very difficult to leave and you may regret your original decision – with no way out.
With that said, perhaps the best place for chutznikim these days is Ramat Beit Shemesh. There is a strong “chutznik society” there and this should make it easier.
