How is citizenship achieved in the united states

3 Types of Colonial Naturalization

Denization--A type of naturalization used to obtain land.  You could buy and sell land, but could not hold public office. There were no political privileges associated with denization.

Oath of Allegiance--This type of naturalization during the colonial period was used to renounce all former country loyalties.  This gave the immigrant full privileges, including voting and holding public office.

Collective citizenship--This naturalization process was used to naturalize a group of people without using documents.  Collective naturalization happened when the United States became a country in 1776 and all those living in the country (except Native Americans and African Americans) were collectively and automatically made US citizens.
