Clearances
So it is understood that Emirates will need you to clear all the guarantees they have in their system before your release. That seems pretty straightforward.
Did anyone who has resigned looked further than that to avoid any unpleasantness at the airport on the day of departure? By this I mean is it possible some long-forgotten business arrangement or credit card could be hanging in the background and associated with one's residence visa such that when one went to leave you were held back?
If one wished to display an excess of caution is there a method to check such a thing before the actual day of leaving?
