Naturalization is the legal process our immigrant ancestors went through to become citizens of the United States. Becoming naturalized meant our foreign-born ancestors could vote, run for a government office, serve on a jury, pay taxes, receive the protection of the law. The process of applying for citizenship generally consisted of three major steps: Declaration of Intent - First Papers. The declaration of intent to become a citizen is sometimes referred to as the "first papers". Petition for Naturalization - Second or Final Papers. After meeting the residency requirements (2 years from 1790-1795, 5 years from 1795-1798, 14 years from 1798 to 1802, and 5 years from 1802 to present) an immigrant could petition the court to become a citizen. Certificate of Citizenship- After all requirements were completed, the immigrant was sworn in as a citizen and issued their certificate.
