Polish workers are the largest group of "foreign workers" in Norway, according to the country's immigration agency UDI (Utlendingsdirektoratet).

This has led to many Polish workers applying to bring their families in to Norway, said the UDI.

In the first three months of the year, 1,015 family immigrant permissions were granted to Polish citizens. This is almost double the number in the same period of 2007.

In total, 4,800 have been granted permission so far this year, 25 percent more than during the same period last year.
