U.S.C. § 951(d). The crime defined by Section 951 is complete upon knowingly acting in the United States as an unregistered foreign-government agent. 18 U.S.C. § 951(a). The statute does not require willfulness, and knowledge of the notification requirement is not an element of the offense. United States v. Campa, 529 F.3d 980, 998-99 (11th Cir. 2008); Duran, 596 F.3d at 1291-94; Dumeisi, 424 F.3d at 581. The Foreign Agents Registration Act (FARA) generally makes it illegal to act as an agent of a foreign principal by engaging in certain (largely political) activities in the United States without registering with the Attorney General. 22 U.S.C. §§ 611-621. The triggering agency relationship must be with a foreign principal or “a person any of whose activities are directly or indirectly supervised, directed, controlled, financed, or subsidized in whole or in major part by a foreign principal.” 22 U.S.C. § 611(c)(1). That includes a foreign government or political party and various foreign individuals and entities. 22 U.S.C. § 611(b). A covered relationship exists if a person “acts as an agent, representative, employee, or servant” or “in any other capacity at the order, request, or under the [foreign principal’s] direction or control.” 22 U.S.C. § 611(c)(1). It is sufficient if the person “agrees, consents, assumes or purports to act as, or who is or holds himself out to be, whether or not pursuant to contractual relationship, an agent of a foreign principal.” 22 U.S.C. § 611(c)(2). The triggering activity is that the agent “directly or through any other person” in the United States (1) engages in “political activities for or in the interests of [the] foreign principal,” which includes attempts to influence federal officials or the public; (2) acts as “public relations counsel, publicity agent, information-service employee or political consultant for or in the interests of such foreign principal”; (3) “solicits, collects, disburses, or dispenses contributions, loans, money, or other things of value for or in the interest of such foreign principal”; or (4) “represents the interests of such foreign principal” before any federal agency or official. 22 U.S.C. § 611(c)(1). It is a crime to engage in a “[w]illful violation of any provision of the Act or any regulation thereunder.” 22 U.S.C. § 618(a)(1). It is also a crime willfully to make false statements or omissions of material facts in FARA registration statements or supplements. 22 U.S.C. § 618(a)(2). Most violations have a maximum penalty of five years of imprisonment and a $10,000 fine. 22 U.S.C. §
