An Independent TD says Irish citizens living here should get priority over those in the UK when applying for a passport.
It follows a huge increase in the number of Britons looking for an Irish passport in the wake of the Brexit vote.
50 applied in 2014 - compared to 860 last year.
Mattie McGrath says delays in the passport office is having a huge impact.
He said: "I know there is a huge influx from the UK in advance of Brexit.
"I honestly feel we should look after our own first, many people applying from the UK already have a British passport."
