I would like to echo what onlyemes said, and add a caveat. Talk to the people at Nefesh b’Nefesh, and talk to your local Aliyah Shaliach. Ask the same questions to both. And keep in mind that when you actually do get here, the information you were given may not be totally accurate.
That said, I think every Jew should live in EY. Despite some of the problems that crop up during the Aliyah process, living here is an indescribable bracha and well worth whatever it takes to get here.
