Around 5,400 people will be granted Irish citizenship across six ceremonies in Dublin this week.
The ceremonies across Thursday and Friday will see applicants from 143 countries and living in 30 counties on the island of Ireland being conferred as Irish citizens.
It means that, in total, 10,000 people will be conferred with Irish citizenship this month after 4,800 people attended ceremonies in Killarney last week.
Simon Harris, attending his first citizenship ceremony as Taoiseach, said they are “magnificent celebrations of all that it is to be Irish”.
Speaking at the Convention Centre in Dublin, Mr Harris said: “The richness of our nation isn’t measured in wealth. It is measured in people. Our newest citizens are part of us, and we of them.
“I am very grateful to those who have made Ireland their home. They contribute to the rich fabric of our nation and make exceptional contributions in a range of areas – from health and home care, to culture and construction, to transport and tourism.
“I am very grateful to each of our new citizens for choosing Ireland as the home of their hearts and the home of our future.”
Asked by reporters if he felt that Ireland had become a less welcoming place amid a growth in anti-migration demonstrations, Mr Harris said: “I believe this is still a very welcoming country and I believe we should never allow a very, very, very small number of people to suggest they speak for the majority or suggest they speak for Ireland.
“If you want to speak for Ireland, you run for election and that’s the way you decide who gets to speak for our country.
“Of course, we have – and we shouldn’t be ignorant to the fact that we have – seen a rise in recent periods of time in terms of anti-migrant sentiment and we should always push back against that.
“I think the best way a government of the centre pushes back against that is by one: calling it out, but secondly: ensuring that the compassion that we have in this country for people who come here and seek our assistance and seek refuge is also matched by a common sense, rules-based efficient migration system.”
Justice Minister Helen McEntee also attended Thursday’s events.
Ms McEntee said: “My heartfelt congratulations go out to all our newest citizens conferred at this week’s citizenship ceremonies. Ireland is all the better for having you here and you are valued members of our society.”
Founder of the Irish Muslim Council, Shaykh Dr Umar Al-Qadri, was among those receiving Irish citizenship.
In a statement, he said: “I’m proud to have become an Irish citizen from today. Thank you, Ireland.”
