Portuguese nationality law

Portuguese nationality law is the legal set of rules that regulate access to Portuguese citizenship, which is acquired mainly through descent from a Portuguese parent, naturalisation in Portugal or marriage to a Portuguese citizen.

In some cases, children born in Portugal to non-citizens may be eligible for Portuguese citizenship. However this does not apply to children born to tourists or short-term visitors. Portuguese citizenship law is complicated by the existence of numerous former colonies and in some cases it is possible to claim Portuguese citizenship by connection with one of these jurisdictions. The most notable of these are Portuguese India (annexed by India in 1961), East Timor and Macau.

Overall the present Portuguese nationality law, dated from 1981, privileges Jus sanguinis, while the precedent law, of 1959, was based on the principle of Jus soli. This shift occurred in 1975 and 1981, thus basically making it difficult to access naturalization not only to first generation migrants, but also to their children and grandchildren. Only very recently, in 2006, was this situation slightly changed, but still stressing Jus sanguinis.
