I think they can be the real deal. I’m not in business yet, but I first heard of virtual assistance because I responded to an ad titled, “Administrative Assistant (virtual)”. I grasped that the position was virtual, but didn’t realize there was an entire VA world out there!
The lady called me, and it turns out we knew each other slightly because we both worked at the same company several years ago! She has since opened her own business and needed a virtual assistant. It wasn’t the right fit for me, but it was definitely legitimate.
