Portuguese nationality can be acquired for several reasons.
The nationality can be originating, which happens in the following cases:
Sons of Portuguese mother or Portuguese father born in Portuguese territory;
The children of a Portuguese mother or a Portuguese father born abroad if the Portuguese parent is in the service of the Portuguese State;
The children of a Portuguese mother or a Portuguese father born abroad if they are registered in the Portuguese civil registry or if they declare that they wish to be Portuguese;
Individuals born abroad with at least one ascendant of Portuguese nationality of the second degree in the straight line;
Individuals born in Portuguese territory, children of foreigners, if at least one of the parents is also born here and resides here, regardless of title, at the time of birth;
Individuals born in Portuguese territory, children of foreigners who are not in the service of their State, declare themselves to be Portuguese and provided that at the time of birth one of the parents has been legally resident for at least five years;
Individuals born in Portuguese territory who have no other nationality.
Nationality may also be acquired by virtue of the will, in the case of minor or incapacitated children, of a father or mother who acquires Portuguese nationality by declaration, or, in the case of a foreigner who has been married for more than three years to a Portuguese national, or at the date of the declaration of a de facto union for more than three years with a Portuguese national, after recognition of this situation to be filed in the civil court.
Finally, it is possible to acquire nationality by naturalization to the major foreigners who have been legally resident in Portugal for at least six years, who are sufficiently familiar with the Portuguese language, provided they have not been convicted of a crime punishable by a maximum prison sentence equal to or exceeding 3 years, according to Portuguese law and which do not constitute a danger or threat to national security or defence.
Minors are also granted nationality by naturalization provided that, at the time of application, either parent has been legally resident for at least five years or the child here has completed the first cycle of basic education.
It is also possible to acquire nationality by naturalization to individuals born in Portuguese territory, children of foreigners, who, although they have not been legally resident in Portugal for six years, have usually stayed here in the 10 years immediately prior to the request.
