Dig deeper below to learn exactly what DCSA evaluates, the most common reasons packages get returned, and a step-by-step preparation checklist contractors can use to verify their submission is complete and accurate before it reaches a DCSA reviewer.
When defense contractors think about facility clearance delays, they tend to blame the system: DCSA backlogs, slow investigations, overwhelmed reviewers. But there's another bottleneck that rarely gets the attention it deserves, and it's one contractors can control: the quality of the FCL package itself.
According to DCSA, initial and upgraded FCL packages have a 70% rejection rate, cycling an average of 2.5 times before clearing review. Not because contractors are unqualified, but because submissions contain errors, omissions, or inconsistencies that prevent DCSA from processing them. Every return resets the clock on a process that already routinely takes 180 days or longer.
The consequences are real:
In a market where the Department of Defense (DoD) (also known as the Department of War) has lost 40% of its small business base over the last decade, every avoidable delay raises the barrier to entry that much higher.
The single highest-leverage thing a contractor can do to accelerate their timeline is to get the package right the first time.
The facility clearance process is governed by 32 CFR Part 117 National Industrial Security Program Operating Manual (NISPOM), and the FCL package is the collection of documents a contractor submits through the National Industrial Security System (NISS) after receiving sponsorship from a Government Contracting Activity or cleared contractor acting as a prime.
A complete FCL package typically includes the following core components that DCSA evaluates during review:
DCSA's Facility Clearance Branch (FCB) reviews submitted packages during the Day 20–45 window of the FCL process. An Industrial Security Representative examines whether the documentation is complete, internally consistent, and aligned with NISPOM requirements. If any component is missing, inconsistent, or incomplete, the package is returned to the contractor with a deficiency letter identifying the issues. The contractor must then resolve all flagged items and resubmit—and the review window starts over.
This is the critical point most contractors miss: DCSA isn’t evaluating your eligibility at this stage. They're simply determining whether your paperwork is in order to begin the evaluation. A package return at this stage isn’t a denial; it's an administrative delay caused by a submission that didn't meet the threshold for review.
And it’s almost always preventable.
DCSA's own presentations at industry conferences have identified the top reasons FCL packages are returned. While the specifics vary by case, the same categories appear consistently. Understanding these patterns is the first step toward avoiding them.
This is the single most common source of FCL package deficiencies. The SF-328 requires contractors to disclose all foreign ownership, control, influence, or affiliation, and the definition of each is broader than most first-time applicants expect. Common errors include failing to disclose foreign revenue sources, omitting foreign board advisors who don't hold formal officer titles, and providing information on the SF-328 that contradicts what's shown on the legal organization chart.
DCSA determines KMP based on the contractor's corporate structure, and the list often includes individuals the contractor didn't expect such as passive investors with 5% or greater equity, or board members who don't participate in day-to-day operations. Packages are frequently returned because KMP rosters are incomplete, KMP data doesn't match what's on file in the National Industrial Security System (NISS), or required individuals haven't been submitted for PCL processing. Turnover compounds the problem: if a KMP departs and the contractor doesn't update NISS before submitting, the package arrives with stale data.
The legal org chart submitted to DCSA must match the company's filings with its state of incorporation. This sounds straightforward, but for companies that have gone through mergers, acquisitions, or restructurings, the org chart on file with the state may not reflect current reality, or the version submitted to DCSA may reflect intended changes that haven't been legally completed. Any mismatch between the org chart, the SF-328, and the KMP documentation creates a consistency problem that DCSA must flag.
The DD-441 is a legally binding security agreement, and DCSA requires it to be executed precisely. Common errors include missing dates or submitting the form unsigned or signed by the wrong person (the signatory must be the senior management official authorized to bind the company). These may seem like minor oversights, but DCSA can’t process an improperly executed security agreement, so the entire package is returned until the DD-441 is corrected.
Even when the underlying documents are correct, technical formatting issues in the NISS electronic submission can prevent DCSA from processing the package. Uploading documents in unsupported formats, failing to link KMP records properly, or submitting an incomplete package because required uploads weren’t finalized are all common errors.
Packages are sometimes returned two or three times because the deficiencies from the previous return letter have only been partly addressed. DCSA issues detailed return-reason correspondence identifying every item that requires correction. Contractors who treat this as a partial checklist—fixing the obvious issues while overlooking others—end up in a cycle that extends their timeline by months.
All these errors are preventable. They stem from institutional knowledge gaps, manual preparation processes that lack a built-in verification layer, and the simple reality that many contractors—especially smaller ones entering the Defense Industrial Base (DIB) for the first time—are assembling FCL packages for the first time without support. The FCL process doesn't offer a pre-submission review or a "check my work" mechanism. What you submit is what DCSA evaluates, and if it's not right, you won’t know for weeks.
That's exactly the problem ISI and DARPA set out to solve. DARPA selected ISI as one of two firms to develop Facility Control, a platform that applies automated validation logic and AI-assisted document extraction to catch the most common FCL package deficiencies before submission.
On May 12, 2025, DCSA released a significantly revised Standard Form 328: the first major update to the Certificate Pertaining to Foreign Interests in seven years. For contractors preparing FCL packages, this update represents a meaningful increase in the documentation burden, and it introduces several changes that are likely to generate new categories of submission errors.
The key changes that affect FCL package preparation include:
For contractors already in the facility clearance process, these changes mean that SF-328s completed under the old form may need to be updated and that submissions prepared using the previous version's formatting expectations may not meet the new requirements.
For first-time applicants, the expanded disclosure requirements and the legal attestation create additional opportunities for incomplete or inconsistent responses, which flow directly into the deficiency patterns described above.
A returned FCL package has one primary cost: time. And in this market, time converts directly to lost revenue and competitive position.
Here is what the math looks like in practice:
The backlog and the macro environment are outside your control. The completeness and accuracy of your FCL package is not. Every preventable error that triggers a return is time your competitors may be using to get cleared ahead of you.
This checklist is organized around the core components of an FCL package. It's designed to be used as a pre-submission self-audit: a final verification pass before you transmit your package through NISS.
None of these checks replace the guidance of an experienced FSO or compliance advisor, but they address the most common deficiency triggers and give contractors a structured way to catch errors before DCSA does.
Contractors typically take one of three approaches to FCL package preparation:
ISI has worked with 900+ defense contractors on FCL preparation and maintains a 99% FCL approval rate and a 53-day average turnaround, backed by a team of 50+ certified FSOs, including through Facility Control, the ISI DARPA-backed pre-submission validation platform.
A Facility Clearance is an administrative determination by DCSA (Defense Counterintelligence and Security Agency) that a company is eligible to access classified information at a specified level. Companies cannot perform on classified government contracts or access classified materials without one. The FCL process involves submitting a package of governance, ownership, and personnel documentation for DCSA review.
The overall FCL timeline — from sponsorship through DCSA approval — typically ranges from three to six months, though complex cases involving foreign ownership (FOCI) can take longer. Our Facility Control platform addresses the part of that timeline you control: preparing a complete, accurate submission package. A well-prepared package reduces avoidable delays caused by incomplete information or inconsistent data across forms.
DCSA's published framework outlines a 45-day processing window, but the actual end-to-end timeline from sponsorship to clearance issuance averages around 180 days or longer. Timelines vary based on the complexity of the contractor's corporate structure, the speed of KMP personnel clearance investigations, FOCI mitigation requirements, and DCSA's current workload. Package returns for documentation deficiencies can add 30 to 60 days or more per cycle.
The most common reasons for FCL package returns are incomplete or inconsistent FOCI disclosures on the SF-328, KMP documentation gaps, legal organization chart errors that don't match state filings, DD-441 execution issues (wrong signatories, missing dates), and NISS submission errors. DCSA issues a return-reason letter identifying all deficiencies, and all items must be resolved before resubmission.
The SF-328, formally titled the Certificate Pertaining to Foreign Interests, is a required component of every FCL application. It discloses the contractor's foreign ownership, control, influence, and affiliations. The form was significantly updated in May 2025 with expanded disclosure requirements and a new legal attestation. The updated version also extends to SBIR/STTR programs and unclassified DoD contracts over $5 million.
A complete FCL package typically includes the SF-328 (Certificate Pertaining to Foreign Interests), DD Form 441 (Department of Defense Security Agreement), Key Management Personnel documentation and identification, a legal organization chart matching state filings, FOCI disclosures and supporting documentation, and any additional materials required based on the contractor's business structure. All documents are submitted electronically through NISS.
Yes. ISI provides managed security services that include full FCL package preparation, submission management, and an ongoing DCSA liaison. Our team of 50+ certified FSOs has achieved a 99% FCL approval rate across 900+ defense contractor clients. Outsourcing is particularly valuable for first-time applicants, contractors with complex corporate structures, and organizations that have had packages returned and need a more systematic approach to resubmission.
