There are two routes in which a non EEA national can apply for permission to reside in the State on the basis of marriage or civil partnership with an Irish national.
A). If you are a non visa required national who has entered the State legally within the last 90 days or if you are a visa required national and you are within the period of permission to remain granted to you on arrival in the State (except short stay ‘c’ visas):, or if you have current permission to remain in the State on an alternative basis both you and your Irish national spouse/civil partner should attend at your local Garda National Immigration Bureau Registration office with the following documentation:
Your original marriage/civil partnership certificate
Your original passport
Your Irish spouse’s/civil partner’s original passport
Evidence of your joint address
B). If you do not have current permission to remain in the State a written application must be made to the following address:
Spouse of Irish National Unit, Residence Division,
3rd Floor,
Irish Naturalisation and Immigration Service,
13-14 Burgh Quay,
Dublin 2.
So, if you have a valid stamp 2 than go to your local immigration office with the list of documents mentioned on the below link:
