“What about Israel? See my post above..”
Yes, a new immigrant gets financial assistance with things like housing, discounts on import tariffs, new purchases, ulpan to learn Hebrew, etc, for a limited time, and many communities are warm and inviting and take care of each other. I don’t advise showing up at the airport, but rather contacting Nefesh B”Nefesh state-side, they can advise on what benefits are available for his particular case, what communities might be appropriate, arrange for flight, as well as take care of the paper-work that is needed. I don’t think he would make it on a couple of hundred dollars though, even with assistance, and socialized medicine and other benefits. I know immigrants have come from Ethiopia and elsewhere with almost nothing and have been set up in Israel, but I think this sort of assistance depends on the country of origin, and I don’t know if an American would benefit. Nefesh B’Nefesh would know though.
In any case, do you think it is in his best interest to start over again in a new country/culture/mentality? Does he speak Hebrew?
