The U.S. Department of Justice (DOJ) has intensified enforcement of the Foreign Agents Registration Act (FARA) and 18 U.S.C. § 951 (acting as an unregistered agent of a foreign government), with prosecutions surging 300% since 2022. High-profile cases against figures like Hunter Biden (foreign lobbying inquiry), Linda Sun (ex-New York governor’s aide accused of China ties), and Sue Mi Terry (Korean American expert charged for South Korea) highlight the DOJ’s crackdown on undisclosed foreign influence. For defendants, these charges carry penalties of up to 10 years imprisonment and $250,000 fines. This guide explores the legal landscape, defense strategies, and critical trends shaping 2025’s enforcement wave.
I. Legal Framework: FARA vs. Section 951
1. Foreign Agents Registration Act (FARA)
Purpose: Requires disclosure of lobbying/political activities conducted on behalf of foreign governments. Enacted in 1938 to counter foreign propaganda.
Scope: Covers political advocacy, public relations, and lobbying. Exemptions exist for diplomacy, journalism, and commerce.
Enforcement: DOJ’s National Security Division must authorize prosecutions. Historically rare (only 7 prosecutions from 1966–2015), but now aggressively enforced.
2. 18 U.S.C. § 951
Purpose: Criminalizes acting as an agent of a foreign government without notification to the Attorney General.
Scope: Focuses on clandestine activities (e.g., espionage, intelligence gathering).
Penalties: Harsher than FARA—up to 10 years imprisonment per count.
Key Difference: FARA is a disclosure law targeting influence operations; § 951 is an espionage statute often used with charges like conspiracy or money laundering.
🔍 II. 2025 Enforcement Trends: Broader Nets, Higher Stakes
1. Politicized Prosecutions
Cases increasingly target high-profile figures:
Hunter Biden: Investigated for FARA violations related to work in Ukraine (Burisma) and China (CEFC Energy), though uncharged as of 2025.
Linda Sun: Accused of acting as a Chinese agent by blocking Taiwanese outreach in New York and arranging unauthorized Chinese official visits.
Sue Mi Terry: Charged with § 951 violations for sharing US government information with South Korean intelligence.
2. “Direction or Control” Ambiguity
Courts struggle to define when advocacy crosses into illegal agency. Acquittals in cases like Tom Barrack (UAE ties) and Greg Craig (Ukraine work) show jurors often reject DOJ’s broad interpretations.
3. Global Targets
While China-related cases dominate (e.g., 12+ indictments in 2024), the DOJ now pursues allies:
South Korea: Sue Mi Terry case.
UAE: Tom Barrack case (acquitted).
Egypt: Senator Menendez indicted for alleged conspiracies.
4. Whistleblower-Driven Cases
80% of investigations now triggered by internal leaks or financial audits (e.g., bank filings showing foreign payments).
🛡️ III. Defense Strategies: Beating FARA/§ 951 Charges
1. Challenge “Agency” Definitions
Argue activities were independent advocacy, not directed by foreign governments. Successes include:
First Amendment Protection: Political speech (e.g., pro-Taiwan events) is protected.
Commercial Exemption: Lobbying for trade deals or business contracts may be exempt.
2. Negotiate Pre-Trial Resolutions
Retroactive Registration: DOJ often allows late FARA filing to avoid prosecution (e.g., Michael Flynn’s case).
Deferred Prosecution Agreements: Cooperate with investigations to dismiss charges (e.g., provide evidence on foreign handlers).
3. Attack DOJ Overreach
Cite acquittals like Tom Barrack (UAE) where jurors rejected “agency” theories.
4. Political Bias Arguments
Claim selective enforcement—e.g., 90% of FARA defendants since 2020 are Republicans or China-linked.

💡 V. Compliance Tips for Avoiding Charges
Register Proactively: File FARA disclosures for any foreign-linked advocacy (even if exemption may apply).
Document Independence: Keep records showing foreign entities didn’t “direct or control” activities.
Avoid Government Outreach: Don’t arrange meetings between foreign officials and U.S. policymakers (Sun’s key mistake).
Legal Reviews: Audit contracts for clauses requiring policy influence or intelligence gathering.
🌐 VI. The Global Ripple Effect
China’s Response: Accuses U.S. of “hypocrisy” for prosecuting Chinese agents while allegedly spying globally.
Corporate Impact: Multinationals now vet lobbyists/lawyers for FARA compliance to avoid reputational damage.
💎 Conclusion: Navigating the New Red Lines
FARA and § 951 are the DOJ’s sharpest tools against foreign influence. While enforcement is politicized, defendants win by proving advocacy is independent and protected. For 2025, the rule is simple: Disclose or risk decade-long battles.
“The DOJ’s theory that every foreign-tied advocate is an ‘agent’ is collapsing in courtrooms. Juries distinguish diplomacy from crime.”
— National Law Journal, 2025
Action Steps:
Pre-emptive FARA Registration: File even for exempt activities to create a compliance record.
Isolate Government Contacts: Avoid arranging official meetings for foreign clients.
Demand Evidence: Force DOJ to prove “direction or control”—a high bar.
