Civil partnership legislation means that civil partners are eligible to apply for citizenship for the non-Irish civil partner or spouse after 3 years of civil partnership or marriage, the same as applies for opposite-sex married couples.

It is possible to become a citizen of Ireland through marriage.

As a result of Civil Partnership legislation, this has been extended to include lesbian and gay couples in civil partnerships, who can now apply for their non-Irish partner to become a citizen of Ireland after three years of civil partnership, the same as married opposite-sex couples.

Irish civil partnership legislation automatically recognises almost all foreign legal same-sex marriages and civil partnerships as Irish civil partnerships. The provisions of citizenship that come with Irish civil partnership apply equally to these foreign relationships.
