My advice is to go to the dea website and read that information for yourself. In order to import medications from other countries (other then carrying 3 months supply over the border i.e. Mexico or Canada) you would have to apply for a personal importation license from the dea which is about imposible to get. You would also have to have this license BEFORE you import medications is does not work after the fact. My best advice to you is if you get a love letter simply ignore it, to respond is only asking for trouble.
