The company I think can stop the clearance process but doubt they'll even think about that when you leave. The paperwork is in the system and most likely a result will be produced (cleared or uncleared). Still, at least if you fail you won't have to do the walk of shame when being escorted off site

So if you do leave the company, contact the DVA to ask about it at a time when you think by then the clearance should have been granted. Don't contact them early in case they stop the process because you are no longer working for x company
