Foreign Investment and National Security Act (2007)

The Foreign Investment and National Security Act of 2007 formalised and revised procedures for national-security review of foreign investment by the Committee on Foreign Investment in the United States. It built on the Exon-Florio Amendment (1988). The current regime is FINSA as materially amended by FIRRMA (2018), later legislation, regulations and executive direction.

Historical contribution

FINSA codified the interagency CFIUS, established reporting and accountability requirements, and revised review and investigation procedures. Its 2007 structure should not be presented as the complete current jurisdiction. FIRRMA expanded coverage to certain non-controlling investments and specified real-estate transactions and changed procedures, declarations and resources.

Current rules are principally found in 31 CFR Parts 800 and 802, supplemented by amendments and Executive Order 14083's national-security factors. Transaction advice requires those live authorities rather than FINSA alone.

Committee and presidential roles

CFIUS receives declarations and notices, conducts review and investigation, negotiates mitigation, monitors compliance and can address non-notified transactions. A short-form declaration, full notice, review, investigation, mitigation agreement, enforcement action and referral are separate stages.

The committee can clear a transaction or negotiate mitigation within its authority. The President holds the statutory power to suspend or prohibit a covered transaction on the required findings. A presidential order is therefore not simply a committee decision, and committee concern is not an adjudicated violation.

Current reporting

Treasury's latest published annual report at the status lock covers calendar year 2024. Any caseload number should identify declarations, notices, investigations, mitigation agreements, penalties or non-notified reviews separately and preserve the report year. Filing counts are not equivalent to prohibited transactions or findings of espionage.

Strategic scope

CFIUS can limit ownership, access, governance or data exposure in sensitive businesses. It is an inward-investment screening regime, distinct from Outbound investment screening. Strategic effect depends on transaction structure, mitigation, investor substitution and whether protected capability remains available through other channels.

Criticism that review is protectionist is an analytical claim, not established by a filing count. Assessment should identify the covered transaction, foreign investor, control or access rights, national-security concern, committee action and final disposition. As at 30 July 2026, Parts 800 and 802 and current Treasury guidance control.

Transaction pathway

Parties may submit a declaration or full notice, while CFIUS can request a notice or examine a non-notified transaction. Acceptance, review and investigation are procedural stages, not findings that the transaction threatens national security. Withdrawal and refiling can reflect unresolved questions, changed terms or timing and should not be coded automatically as prohibition.

Mitigation can restrict information access, governance, supply relationships, facilities or personnel and may require monitoring. A mitigation agreement permits a transaction subject to conditions; it is not clearance without concern. Penalties for breach require their own notice and final status.

Real-estate jurisdiction under Part 802 differs from covered-business jurisdiction under Part 800. Location near specified sites, foreign-government interest and excepted-investor status must be tested under the correct rule. These distinctions are essential to current caseload and effect claims.
