Telework

My husband is in the middle of the recruitment process and it's going well. I am a female college professor who will have the option of teaching online in degree programs at a university in the US after I resign here. I will therefore be working from home. Does anyone know if this would require a visa or some type of special permission from KSA? I understand that I probably won't get a job in KSA so I'm thinking of ways in which I can remain engaged in my profession (Clinical psychology). I have asked the recruiter but apparently no-one has ever asked about teleworking abroad before... (: any help would be very much appreciated.
