Is money earned from working for a year in an unlicensed document photocopying shop halal or haram?

The money you earned from a permissible job—in itself—such as document photocopying, is permissible money, and there is no sin upon you in possessing it. However, you sinned by not obtaining a license for this work, because the laws of the lands that a Muslim enters by covenant and that do not contradict Islamic law oblige him not to violate them, due to the Almighty’s saying: "And fulfill the covenant; indeed, the covenant will be questioned."
