1 dez 1789 ano - The 1790 Naturalization Act (1 Stat. 103)
establishes the country’s first uniform
rule for naturalization. The law provides
that “free white persons” who have
resided in the United States for at least
two years may be granted citizenship,

moral character and swear allegiance
to the Constitution. The law also
provides that the children (under 21)
of naturalized citizens shall also
become US citizens.
