@Sbusquirrel,
Thank you for the reply. I reviewed the SF-86 and it does only state 10 years. But further down it does ask about federal employment that was not previously noted (in the 10 year window). So, once I note it in there I would venture to guess it is going to come up. My hope is that since it will have been 10 years and I have had a very successful career since then that I will be granted the TS/TCI during the SSBI.
