In addition to the question of a child's citizenship, there is also a question of how to report "Place of Birth" for children born in transit. US State Department guidance instructs that a child born in international waters should have their place of birth listed as "AT SEA", while those born in the territorial waters of any country would list the name of that country.[4] A child born in flight in a region where no country claims sovereignty would list their place of birth as "IN THE AIR".[4]
