My understanding of what the minister said and of how the rules apply is that FATCA is applicable potentially to U.S. taxpayers, including U.S. residents--according to our concept of the term—as well as U.S. citizens. So a dual citizen could be subject to the application of the intergovernmental agreement, but it requires them to be a U.S. citizen.
