I joined the Armed Services and will need a Top Secret clearance for my MOS(job).  I filled out the SF-86 and did not list two vacations to foreign countries(my recruiter told me not to list any travel under the age 16.)  When I was about 12 I went to Mexico. 
However, I did not list travel to the Bahamas because I thought I was 15 at the time.
I now realize that I may have been 16 at the time,and I have a couple of questions:
1. Was my recruiter correct in instructing me to omit foreign travel before age 16?
2. What should I do if I think I may have been 16 when I went to the Bahamas?
Any help is greatly appreciated!

I believe I was supposed to go back 7 or 10 years for my SF-86, but I didn't have to go back further than age 18 unless I was 18-19.  If I had been 18, I was supposed to go back 2 years until age 16.... if 19, to age 17, and if 20 until age 18.  After age twenty and up, I just had to go back to age 18.  Basically I had to go back at least two years but never before age sixteen for the forms.  Later on though, they asked me various questions about other things that I didn't have to put down before.  I saw a counselor when younger, but that didn't come up until the security interview.  They seemed to really understand why I hadn't said I had seen a counselor so I wouldn't sweat it.  Just contact the recruiter, .
