Naturalisation as a Brazilian citizen
Foreigners may apply for Brazilian citizenship if they meet the following criteria:
*permanent residence in Brazil
*four years continuous residence in Brazil (short trips may be permitted)
*ability to speak and write Portuguese
*sufficient personal or family resources to support themselves
The residence requirement may be reduced in certain circumstances:
only one year's residence is required for those who have a Brazilian spouse, parent or child
for nationals of Portuguese-speaking countries, one year's residence is required
those with "professional, scientific or artistic ability" may apply after two years
persons of higher net worth may apply for Brazilian citizenship after 3 years.
Foreigners who have resided continuously in Brazil for 15 years may apply for Brazilian citizenship on that basis alone.
