Frequently Asked Questions
Can I speed up the clearance process?
You can minimize delays by completing the SF-86 thoroughly and accurately the first time, having all required documentation ready, resolving financial issues before applying, and being responsive to investigator requests. However, you cannot directly speed up the government's investigation timeline.
What if my clearance takes longer than expected?
Clearance processing times vary significantly based on individual circumstances, investigation backlog, and the complexity of your background. Foreign contacts, extensive travel, financial issues, and employment gaps can extend timelines. Most employers are understanding about delays and will keep you employed on uncleared work.
Can I work while my clearance is being processed?
Yes. Most Space Coast defense employers will start you on uncleared work or assign you to an unclassified program while your clearance processes. Some positions may grant an interim clearance (especially at the Secret level) that allows you to begin classified work earlier.
What is the difference between an initial investigation and a reinvestigation?
An initial investigation is conducted when you apply for a clearance for the first time. A reinvestigation (also called periodic reinvestigation or PR) is conducted to renew an existing clearance — every 10 years for Secret and every 5 years for Top Secret/TS/SCI. Reinvestigations are typically faster because your baseline has already been established.
Does having a prior clearance speed up getting a new one?
If your clearance lapsed within the past 24 months, it can be reinstated without a full reinvestigation, which is significantly faster (typically 1–4 weeks). If more than 24 months have passed, a new investigation is required, but your prior clearance history is viewed favorably.
