MOST of the more than 5,000 callers to the Immigrant Council of Ireland (ICI) hotline last year sought information on becoming Irish citizens.
In total, the council received enquiries from 145 different nationalities in the 11 months from January to November.
Other top issues included work permits, residency rights and queries on becoming an international student here.
The council also revealed that there were 64,334 visits to its website recorded in the period, with new visitors accounting for two-thirds of hits.
Denise Charlton, ICI chief executive, said there was a need for a "modern, efficient and transparent system to respond to the needs of people who are already calling Ireland home".
The helpline on (01) 6740200 is open on Monday and Tuesday between 10am and 1pm and on Thursdays from 2pm to 5pm.
