I am advised by my officials in the Irish Naturalisation and Immigration Service (INIS) that there are a number of conditions that must be met before deciding on an application for permission to reside in the State of the type referred to in the Deputy's question.
In the matter of finances, it is not possible to be prescriptive as to what would be considered sufficient income because of the unique nature of each case. However, the underlying principle regarding self-sufficiency is that the foreign national would not need to avail of State funds or State funded services nor would any dependant family member who was allowed enter the State require such State benefits.
In this particular case, I understand that additional supporting information has come to the attention of INIS and they will contact the persons concerned further regarding their application.
