A single source in Vermont is defined as “an individual, partnership, corporation, association, labor organization or any other organization or group of persons which is not a political committee or political party.” 17 V.S.A. §2901(16). Each single source contributes directly to a candidate and money cannot be transferred from one source to another for the purpose of circumventing the contribution limits.
Federal law prohibits the acceptance of campaign contributions from foreign nationals, except when they are lawful permanent residents of the United States. This provision also applies to PACs and parties. 2 U.S.C. §§441e, 441f & 11 CFR 110.20
