Regulations on social security for migrant workers are directly applicable in all EU countries and in those in the European Economic Area - Iceland, Liechtenstein and Norway. The regulations are designed to protect the social security entitlements of persons who move to other member states. They apply to EU and EEA nationals only and do not apply to occupational and personal pension schemes.
If a person to whom the regulations apply takes up employment or self-employment after moving here, he is entitled to have the periods of insurance completed in the other country added to any periods of insurance completed in Ireland to qualify for benefits under legislation, as if these periods completed abroad had been completed in Ireland. Benefits for short-term contingencies such as sickness, maternity and unemployment would normally be paid under Irish legislation and at the Irish rates of payment. This also applies in the case of invalidity pensions where the periods of insurance had been completed in certain EU states, including the United Kingdom.
In the case of pensions for old age, retirement, widowed persons and, in certain cases, invalidity, a pension amount is paid by each country where the person had completed periods of insurance of at least one year. The pension amounts are usually in proportion to the periods of insurance actually completed in each country and are normally referred to as pro rata pensions. Thus, if in a career of 40 years, a person had completed 20 years insurance in each of two countries, he would qualify for a pro rata pension approximately equivalent to half a full pension from each country. However, if he had enough insurance to qualify for a pension in his own right under the legislation of a country, then this pension amount and the pro rata pension amount would be compared and the higher of the two would become payable.
An EU national from another EU country entitled to reside here would also be eligible for other benefits due to residents, such as child benefit, even if the child was living in another member state, benefits under social assistance and health services, provided he satisfies the conditions for entitlement which apply to other residents. If he was already receiving a pension from another member state or became entitled to one while resident here, the pension would be payable to him in Ireland in the currency of the state making the payment. Special rules apply in certain cases to frontier workers such as a person working in Northern Ireland and residing in the Republic of Ireland. For example, if he became unemployed, the benefit due would be paid by the Republic of Ireland.
