Did Castro not give you a cuban passport? Those who did not want Portuguese citizenship went to live in chira bazar and sonapur.
BC Doc, I agree with the contention that if you apply for the citizenship of a country, you should also have to apply to renounce it, when you move on. The problem here is that no one before 1961 could apply for Portuguese citizenship. Portuguese citizenship was forced down our throats. Whether you liked it or not, thanks to Salazar, a person born in Goa was classified as a Portuguese citizen.? This is rather strange (to me.) I would have a tough time renouncing a citizenship that I did not apply for.
