Why would any company require a passport for someone who can literally do the job from their living room in their own country? Obviously requiring a passport would be ridiculous for such employment.

I work for VIPKID and it's the best English teaching job I've ever had! It fits in perfectly with my own full time job schedule. Too bad some people have had bad experiences but hey - one's outlook on life has a lot to do with the way one experiences and perceives such events.
