Is this normal for secrete

My security officer entered my SF86 around May. Around July, my file was closed and it was sent to Adjudicator. Now they are doing a full investigation on me.

So I was wondering is what I am experiencing normal for secrete?

What you have stated makes no sense. The process is this: You fill out the SF-86 and submit it to the security officer who reviews it and submits it to OPM or other investigating agency. Once it is closed then an adjudicator reviews it and decides whether to grant a security clearance or if issues are present, send you a letter of interrogatory and statement of reasons to deny.
