Card Manifest Contents
Cards may include many of the following items of information:
 * Keeping statistics on alien arrivals at U.S. land borders was not required by early immigration acts. Thus, statistical treatment of Canadian and Mexican border immigrants at times has differed from that of other immigrants.
 * When records of arrivals began to be kept at the Canadian border in 1895 and at the Mexican border, ca. 1906, the immigration authorities found it impractical to collect arrival information on lists as they did for ship passengers. Therefore, separate cards or "card manifests" for each person were used instead.
 * When viewing these cards it is important to check the reverse side of the card. The "back side" of the card many include instructions about the card, lists of multiple entries into the U.S. for the individual, or an attached photograph.
