The figures, slipped out to MPs in a parliamentary written answer, come as the immigration service came under a fresh attack for its inability to efficiently tackle illegal migrants.
John Vine, the chief inspector of the UK Border Agency, said last week that the public report immigration abuses at a rate of 300 a day but officials were not even able to tell him how many calls resulted in action or an arrest.
Since 2003, some 8,948 illegal immigrants have been granted a permanent stay and the rate is increasing.
Up to 2009 the annual approval rate ranged between 700 and 900 a year but increased to 2,061 in that year and 1,774 last year.
There were 5,400 less Irish emigrants in the 12 months to April of this year, as net migration fell for the second consecutive year.
Of the 80,900 people emigrating during this period, 43.6pc were Irish.
Using the latest technology, EPIC Ireland encapsulates the stories of millions of emigrant journeys and how those emigrants impacted on the countries where they made their new home as well as the impact they had on their native country through their fame or infamy.
Visitors to this Dublin attraction will take themselves on a self-guided tour through 21 different galleries as they watch, listen and experience the broad themes of migration, emigrant motivation, emigrant influence and Irish connections that drove the estimated 10 million Irish emigrant journeys overseas.

The future hasn’t exactly been bright for twenty-something’s in recent years.
Proudly proclaimed itself to be the world’s first digital-only museum, EPIC Ireland is a truly immersive experience.
There’s plenty of substance too behind the high-tech sheen as directed by some of Ireland’s foremost historians, genealogists and tourism experts.
In 2005, a report for the Home Office estimated there could be up to 570,000 illegal immigrants in the UK although others have since suggested it could be as high as one million.
