A dedicated immigration unit that will include detention facilities is to be developed at Dublin Airport, the Department of Justice has confirmed.
Work on refurbishing and refitting an existing area at the airport is due to begin in September in conjunction with the Office of Public Works.
The new immigration unit is expected to take ten months to complete and will be under the direction of An Garda Síochána.
The announcement of the new unit follows widely reported complaints by a Brazilian au pair who last week spoke out about her recent detention in prison following her arrival at Dublin Airport.
Paloma Aparezida Silva-Carvalho said she was left "traumatised" after being detained and later taken to jail by gardaí.
Ms Silva-Carvalho had arrived in Ireland to visit a Co Galway family she previously worked with as an au pair.
She has called for a public apology for her detention. However, immigration services say they are confident they made the correct decision in the case.
Ms Silva-Carvalho is due to leave Ireland on Monday after being granted a ten-day stay.
A spokesperson for the Brazilian Embassy said it acknowledges the right of Irish authorities to decide who should be allowed to enter the country, but that holding potential visitors in prisons for immigration issues, as happened in the case of Ms Silva-Carvalho, is a matter of concern.
Chargé d'Affaires André Baker Méio said embassy representatives spoke to the Department of Justice's immigration officers earlier this week about Ms Silva-Carvalho's case and expressed concern and disapproval of the holding of Brazilian citizens in prisons after their entry into Ireland is denied.
He confirmed that a number of other alleged cases of mistreatment have been brought to the attention of the Brazilian Embassy.
He added that the Embassy was informed about the construction of an appropriate facility in Dublin airport.
