A person born outside the Republic of Ireland with a claim to Irish citizenship by ancestry normally has to register his or her birth in the Foreign Births Register in Dublin in order to acquire Irish citizenship. This process is normally done online. See


To register your birth your parent must have been Irish citizen at the time of your birth. This is usually the case if:

  1. your grandparent was born in the Republic of Ireland before 1987,
  2. your parent had his or her birth registered in the Foreign Births Register before your birth or before 1987, or,
  3. your parent held an Irish passport validly issued before your birth.

In all other cases you would need to prove that your parent was an Irish citizen at the time of your birth, potentially by some other means. To find out if this was the case purchase an evaluation and report, and if the outcome is positive you can apply to register your birth.

We recently applied for citizenship for our two children from South Africa. Jamal from Passportia was highly professional and so positive. From the outset he assured us that it was possible despite many other companies saying they could not help us. We are pleased to say that both children are now officially British citizens and I would definitely use Jamal and Passportia again despite the current exchange rate!
