Talk:FamilySearch Indexing: US, New York—Passenger Lists, 1925–1942, Part A, Project Updates
Note: there is a second form being used that does not fit the directions given. It does not collect the nationality of non-americans. I suggest you mark the field as blank in this case.
The project instructions tab has an example of how to index the documents labelled "List of United States Citizens". https://indexing.familysearch.org/projects/USNewYorkPassengerLists19251942PartA/examples/images/Example42.jpg
It states "This is an example of a passenger list of United States citizens. Unless a location outside the United States was indicated in the place of birth column, for images with this kind of column heading, you should index United States in the Place of Birth or Nationality field for each record on the page." --April Robertson - Owner of Indexer's Point of View 20:11, 16 September 2012 (UTC)
