I wonder: when you enter Israel on a work visa (B1), what's the rules on (a) employment and (b) extension?
Is it anything like the USA system where your stay is initially tied to the employment with a sponsor company (hence if you leave your job you must find work with another H1-B sponsor quickly)? Or is it more like the EU system where any similar job with another company will do?
As for extension, is there ever the prospect of the temporary work visa status turning permanent, or even yielding Israeli nationality? Or is Jewish aliyah the only way to permanent citizenship?
