Birthright citizenship is a hot topic these days,especially for people like Daryl Metcalfe, a Republican from Pennsylvania wanting to bring an end to "the immigrant invasion". So far, they've gathered together to declare the children of illegal immigrants born in the United States at a loss for American citizenship, not establishing which citizenship they should acquire. Thus barring United States citizenship, all others are available by wish and volition: Principality of Monaco's, Lichtenstein's, Azerbajani,Ugandan, even, why not, Martian or Venusian since the decision,at the moment of birth, is obviously up for grabs. Astrological signs may play a part in the decision making process. In case the citizenship is determined by the parents', those from two different countries will have ambiguous choices made for them, again, as long as it isn't U.S.'
