Who uses CFIUSCheck

CFIUS Counsel

Jurisdictional triage at intake

Determine at intake whether a real estate transaction warrants voluntary Part 802 analysis. Replace manual lookups with a verified, timestamped primary-source report suitable for client files and regulatory submissions.

M&A Attorney

Foreign agricultural acquisition screening

Screen target parcels during due diligence for CFIUS and USDA AFIDA reporting obligations before closing. Identify ICBM field county exposure that standard title review misses.

Real Estate Counsel

Foreign buyer transaction support

Advise foreign national and foreign entity buyers on CFIUS proximity implications before contract execution. Generate documentation for the file and provide a defensible basis for your advice.

Compliance Officers

Portfolio monitoring

Run proximity analysis across existing foreign-owned agricultural portfolios following Appendix A expansions. The December 2024 update changed coverage for installations in multiple states — the regime history analysis shows which parcels were affected.

Built on peer-reviewed research

CFIUSCheck is the analytical tool derived from a nine-paper research programme on U.S. supply chain vulnerability and foreign investment disclosure architecture. The underlying research has been formally submitted to the USDA AFIDA ANPRM (Docket USDA-2026-0001) and the Treasury CFIUS Known Investor Program RFI (TREAS-DO-2026-0067).

Frequently asked questions

Is this legal advice? +

No. CFIUSCheck provides factual distance measurements against official government datasets. It does not constitute legal advice, a legal opinion, or a determination of CFIUS filing obligations. CFIUS jurisdiction depends on multiple factors beyond proximity, including transaction structure, the identity of the foreign person, and applicable exemptions. Always consult qualified CFIUS counsel for filing determinations.

How current is the data? +

The CFIUS Appendix A installation list reflects the December 2024 revision (the most recent as of this writing). Installation coordinates are from the DoD MIRTA dataset, August 2025. USDA AFIDA holdings data is from calendar year 2024. We notify Law Firm Plan subscribers when the dataset is updated following a regulatory revision.

How is distance calculated? +

Distance is calculated using the Haversine great-circle formula from the query point (parcel centroid) to the centroid of each installation in the Appendix A database. This is point-to-point measurement. For large installations, the actual boundary-to-boundary distance may be shorter. The Haversine result is conservative for determining threshold proximity and is noted as such in the report methodology section.

What is the Part 3 ICBM county check? +

31 CFR Part 802 Appendix A includes 48 counties associated with the three active ICBM missile wings: the 90th Missile Wing (F.E. Warren AFB, covering counties in Colorado, Nebraska, and Wyoming), the 341st Missile Wing (Malmstrom AFB, Montana), and the 91st Missile Wing (Minot AFB, North Dakota). Coverage for these counties is county-level, not radius-based. If you provide a county FIPS code, CFIUSCheck checks it against this list. The tool identified Chinese-linked AFIDA holdings in Weld County, Colorado (90th MW), which is one of the findings formally submitted to USDA and Treasury.

Can I use this for client filings? +

Reports may be used as supporting documentation in client files and due diligence records. They are generated from primary-source government data, are timestamped, include a unique report ID, and cite their methodology in detail. They are not a substitute for legal analysis by qualified CFIUS counsel. Many practitioners use proximity analysis tools as a starting point for their own independent assessment; CFIUSCheck is designed to serve that function efficiently.

How does the Law Firm Plan work? +
