If a person was at least eighteen, had entered the United States lawfully, and wanted to become a U.S. citizen, they could file a Declaration of Intention at whatever office was in charge of the naturalization process. There was no minimum period of residency requirement to submit this document.
If the person wishing to declare their intent to become a U.S. citizen arrived in the U.S. after 29 Jun 1906, then a Certificate of Arrival was needed, stating that they entered the U.S. lawfully and had been admitted for permanent residence.
A Petition for Naturalization could be filed during a period of two to seven years after the Declaration of Intention had been filed. If the Petition for Naturalization was approved, the petitioner became a citizen after swearing an Oath of Allegiance. In the 1940's, the Petition for Naturalization and the Oath of Allegiance were on obverse sides of the same document.
