There are multiple documented instances of this happening where Israel is the one who denies the visa or fails to provide it.

From a cursory reading[1], it seems Israel had for a long time the ability to veto any human's exit from Gaza through the Rafah crossing in Egypt. Seems to only be the last 5 years where they were not able to do this and that border crossing was open. I graduated from University in 2017.
