I don’t know about US security clearances but for Canadian and NATO ones the key is in the adequacy of all the documentation. Best to hold off on submitting anything until it is all there or the follow up documentation will never catch up to the original application and will delay things.
Contact everyone who you put down as a reference or relative. Tell them that they may be contacted about this. It will lessen the surprise factor when the security people show up.
Warn your neighbors and others like former co-workers and professors. The clearance people will ask your references for other people who would be in a position to know you. This way they get past your hand picked references and get a picture of the real you.
It greatly helps if all your grandparents were born in the country. I know a woman whose grandmother was born on the boat coming from England. There was no documentation of her birth on the ocean, only the landing and immigration records, which did not correspond with the departure records in England. Her clearance took over 18 months to come through and was only an enhanced reliability one.
Another woman actually had relatives, including a grandmother, still living in East Germany (this was in the 80’s during the Cold War), she eventually left the military because she could not get a Top Secret clearance due to the fact that she had visited her grandmother behind the Iron Curtain, when she was a teenager.
Also the less you have moved and changed jobs or schools will help. Fewer facts to check and verify will speed things up.
After I left working for the Canadian military (I was a civilian employee as well.) I was working for a boss who was a micro manager and very insecure in his position (and had a lot to be insecure about as well). I had been referred to the security people because I knew a military officer who was getting vetted for a top security clearance. At that time the RCMP handled the clearances. A RCMP officer came to my work place to interview me. He gave me a business card which I left on my desk, knowing that the boss would be snooping to see who was there. Of course the boss was very interested in why the police was meeting with me behind closed doors. It gave me great pleasure to tell him that he had no need to know.
With the political and military situation as it is today having the clearance in place will make you much more employable in the private sector that deals with this area of government.
Make the best of the downtime, read any manuals that you are cleared to read, read all the textbooks and other technical material that applies to your field.
Just don’t get into the crossword puzzle trap or sooner not later you will have no market value outside the government.
