Return to absorption (idea)
In relation to [immigration]: accomodation to life as a citizen in the state to the point where you no longer need the state's special assistance.
In [Israel], jew immigrants who perform an [Aliya] (employing their law-given [Right of Return]) are eligible for certain state-given assistance:
Eventually the grants run out and by then the immigrant should be absorbed into the country; if not becoming a native then at least not being "rejected" by the country. Being absorbed in the state's terms means earning your living; by the society's terms - not being alien and fitting in. The [Ghetto] dwellers are in the middle between those two definitions.
