See the following announcement, regarding foreign students studying in Israel this. Many have been concerned that if they go back to the USA (or wherever) to be with their extended families for Pesach, they might not be allowed back into Israel after Pesach to continue their studies, as the airport has been only open for returning citizens. It seems arrangements have been made and returning students will be allowed to return. Obviously there are no 100% guarantees of anything, but if the current downward trend of CoronaVirus continues with the upward trend of the vaccinations, it is likely that this should work out well.
