A Palestinian born in Jerusalem with parents and grand-parents buried in its soil can have his "residency permit" revoked if he travels abroad for a couple of years to study or work. This, while anyone in the world (if Jewish) who may never have set foot there is encouraged with generous incentives to "return" and live on confiscated Palestinian lands while receiving automatic citizenship. 

This is in "democratic Israel". In the West Bank, two separate laws apply (apartheid means "separate" in Afrikaaner) one for Jews (civil) and the other for Palestinians (military).
