CFIUS encourages members of the public to report information about potential national security concerns related to foreign investment in the United States.
What to Report
You may submit information about transactions or activities that you believe may raise national security concerns, including:
- Foreign acquisitions of U.S. businesses that may affect national security.
- Foreign investments in U.S. companies involved in critical technologies, critical infrastructure, or sensitive personal data.
- Real estate transactions by foreign persons near military installations or other sensitive facilities.
- Potential violations of CFIUS mitigation agreements or orders.
- Other foreign investment activities that may pose national security risks.
How to Submit a Tip
Tips can be submitted by email to CFIUS staff. All submissions are reviewed by CFIUS staff.
Tip submissions are not CFIUS filings. If you are a party to a transaction that may be subject to CFIUS jurisdiction, please see the Filing Instructions page.
What Happens After Submission
CFIUS staff review all tips submitted through the portal. Due to the confidential nature of CFIUS activities, CFIUS generally cannot provide updates on the status of tip reviews or confirm whether any action has been taken.
If CFIUS determines that additional information would be helpful, CFIUS staff may contact you using the contact information provided in your submission.
Confidentiality
CFIUS treats tip submissions as confidential to the extent permitted by law. Information submitted may be shared among CFIUS member agencies as necessary for the review of potential national security concerns.
Submitting a tip does not create any legal obligation for CFIUS to take action, nor does it establish any legal relationship between the submitter and CFIUS or the Department of the Treasury.
