No, I assume that most of them flew across the Atlantic and went through US border control. We don’t have waves of Norwegians attempting to cross the US borders illegally on ships, like the EU has with African/Middle Eastern immigrants.

There are ample social services and NGO help in the EU that immigrants can take advantage of. Such programs don’t exist in most ME/African countries. Ironically, Norway and other Scandinavian countries do have these programs as well as stable economies.
