Citizenship by Filiation/Descendance (“iure sanguinis”)



The request for recognition of Italian citizenship is allowed upon request by the person concerned, as long as he/she is over 18 years of age, and can be presented, abroad, exclusively to the Consular Office in the country of legal residence.

Appointments for submitting an application for recognition of citizenship by descent and for residual cases of an application for recognition of the automatic acquisition of citizenship by a foreign woman married to an Italian citizen before 27/04/1983 (art.10, law 13.6. 1912 n.555), who has never been the holder of Italian documents or registered in an Italian registry office, can be requested exclusively through the new “Prenot@Mi” portal.

Regulatory notes

The child of parents (father or mother) who are Italian citizens is an Italian citizen. Citizenship is transmitted from parent to child without generation limits, with the condition that none of the ancestors has ever renounced citizenship.

The transmission of citizenship through the maternal line is possible only for children born after 1 January 1948.

The minor child cohabiting with the parent also acquires Italian citizenship on the date on which the latter acquires or reacquires Italian citizenship.

Unlike in the past, the legislation now in force allows you to have dual citizenship, of the foreign country and of Italy.

Starting from 16 August 1992, Italian citizens who acquire foreign citizenship do not lose their Italian citizenship unless they expressly renounce it, except as provided for by international conventions. Prior to that date, loss was automatic. In this case it is possible to repurchase it after at least one year of legal residence in Italy.
