Emergency Travel Document: An Emergency Travel Document is issued by a foreign embassy or consulate specifically for the purpose of travel to the bearer’s home country. It typically has a short validity date (one year or less) and may limit the number of entries. An Emergency Travel Document may be in the form of a traditional passport booklet or may be a single sheet of paper on foreign consulate letterhead.
National identity cards, certificates of citizenship, certificates of naturalization and other civil identity or vital statistics documents are NOT considered travel documents and are NOT valid for entry into or departure from the U.S. by air.
