OFAC does not sanction persons for their engagement in activities subject to U.S. constitutional protection, such as protected speech or religious practice or for their religious beliefs; nor do U.S. persons violate OFAC sanctions for engaging in such constitutionally protected activity. Furthermore, additional limitations and authorizations are in place to ensure that U.S. sanctions do not restrict the exchange of information or informational materials, or personal communication. The majority of OFAC sanctions programs are promulgated pursuant to the International Emergency Economic Powers Act, 50 U.S.C. 1701 et seq., which limits the authority to “regulate or prohibit, directly or indirectly . . . any postal, telegraphic, telephonic, or other personal communication, which does not involve a transfer of anything of value . . . or, the importation from any country, or the exportation to any country, whether commercial or otherwise, . . . of any information or informational materials.” 50 U.S.C. § 1702(b)(1), (3).
No authorization is necessary for U.S. persons to engage in activities that are not prohibited by or are otherwise exempt from sanctions. If you are concerned that potential sanctions may interfere with constitutionally protected activities, please reach out to OFAC for further guidance as described here.
