I am not sure about other companies, but as far as I could tell from Alorica I believe you can work from anywhere as long as you have an internet connection. The position I was just offered requires an AZ license, but you can work anywhere as long as you work the hours that line up with the AZ time zone schedule. The company is global and has centers in many countries, including Mexico. You would have to ask a recruiter for more information. This is what the website states:
