Common Clearance Questions

How long does a clearance take?

Timelines vary by level and complexity. Secret clearances typically take 2-6 months, while Top Secret can take 6-12 months or longer.

Can I get a clearance with bad credit?

Financial issues don't automatically disqualify you. Investigators look at patterns and whether you're addressing your debts responsibly.

Do I need a clearance to apply for jobs?

Many positions accept candidates who are "clearable" - meaning you don't have disqualifying factors. The employer can then sponsor your clearance.

Can past drug use disqualify me?

It depends on recency, frequency, and type. Marijuana use from years ago is often not disqualifying, but recent use or harder drugs may be.
