While in theory Ireland pays the balance of CB to its imigrant workers, the practice is very different.
Example Polish man comes to work in Ireland and applies for CB for his children still living with their mother in Poland. She is immediately contacted by Irish SW and instructed to stop the CB payment (E10 monthly) in Poland.
From date of application to receipt of benefit usually takes up to 21/2 years.
BTW not too many of our migrant workers pay taxes (Income tax) in Ireland as they seem to work mostly for the minimum wage
