This is NOT necessarily an indication of a scam. Many organizations and companies use front addresses for security and to protect privacy. US Asylum Office address, for example, is merely a mail point, with actual location hundreds of miles away in a different state.
I am not sure to which asylum office you refer, as my search engine shows many addresses for subsidiary offices. Locations, locations, locations. Not linked virtual offices. As example: http://myattorneyusa.com/list-of-uscis-asylum-offices
But as to Airfinity and its new announcement of a Denmark address, it turn out that too is a "virtual office," as can be checked.

But.... Nørregade 7B denmark. You might be surprised how many virtual companies, 67 by my count, use this "historic" address. Sustainable cruising and Tibetan Buddhism more....
