There are as many as 1500 PIOs among the Indian community in Brazil, and only 400 NRIs since foreign nationals can acquire local citizenship without any discrimination after 15 years of domicile in this country. Brazil has also no bar against dual citizenship. But in recent years, it has been granting immigration visas only in high technology fields. The only exceptions are the Sindhis in Manaus (who have formed an Indian Association with about a hundred members) and the Goans in São Paulo.
