Fun fact

Did you know that in general work permits in Luxembourg are issued for a maximum of two years in the first instance? If a foreigner intends to stay longer, he/she should reapply, starting the process at least two months before the initial work permit runs out. A reissued visa could be valid for as long as another three years.
