Artur, allow me to clarify a few things regarding a TSC/I Security Clearance... Currently being AD and having a TSC/I Clearance myself, the process is pretty much straight forward and direct... After completion of your SF-86 paperwork/package, it will be reviewed and processed... Once that is accomplished, NCIS (Naval Criminal Investigation Services) will send an agent to ask you questions regarding your Top Secret Clearance... You will be asked questions regarding your association with Foreign Nationals, Credit Report, do you drink alcohol, how often, childhood upbringing, have you ever been fired from a job, how many jobs have you held , criminal records... That's just to name a few... It is basically a check on your creditability... They will have already talked to your references... To make a long story short, despite if you have ever been in any trouble, regarding criminal activity or anything along those lines, just be truthful and honest about it... Think about it, if you have a criminal record, they will know about it, speeding tickets exceeding a 300.00 dollar fine, misdemeanors or anything... Honestly is the best policy... As long as everything is documented you will have no issues being issued a Top Secret Clearance... Definitely good to have Clearance to have... Will be good for up to 5 years and in the civilian sector realm, goes a long way... I know of a lot of "shipmates" who have gotten out of the enlisted ranks because of having a TSC/I and could get a job making 50-60 thousand out in the civilian world just because they have a top secret... Good luck with you Clearance, but you should be fine...
