What exactly is involved with revalidation? Is there anything I need to do during this process? Do I need to constantly update the security people about new places I travel to?
A “revalidation” would probably start with an SF-86C. That is a form where you report anything that has changed since your last investigation, and that is where you could report additional foreign travel.
If there’s nothing on the SF-86C and your travel doesnt involve really dodgy places then they may not even need to do more investigation.
