Once you complete the minimum requirements for a collateral security clearance investigation, you may be granted interim eligibility on a temporary basis, pending the completion of the full investigation for the final clearance. All defense contractor employees are considered for interim clearances. Interim clearances can be withdrawn whenever significant unfavorable information is uncovered about you during the investigation. Interim access eligibility for Sensitive Compartmented Information (SCI) and Special Access Programs (SAP), however, are granted only under very limited circumstances.
