FECL 04 (March 1992):
At present, more than 100'000 foreigners benefit from a regularized situation in Portugal. An additional 100'000 have entered the country illegally. Most of them come from Portugal's former colonies in Africa.
The illegal immigrants must legalize their status within four months and residence permits will only be granted to applicants who have a place of work or sufficient means of existence. Moreover, they must have lived in the country since at least six months. Preferential treatment will be granted to nationals from the former colonies Angola, Mozambique, Guinea-Bissau, Cap Verde and Sao Tome and Principe.
