You can do this from anywhere. I’m not even in the USA myself, not a resident and not a citizen! I visit – but that’s it.
One question I get a lot is “Is this worldwide or only the USA?”
The thing about working online is you can do it from anywhere in the world as long as you have a computer and internet!
I do this all from the Caribbean and I have students in the USA, Australia, Africa, the UK, Canada, Asia, the Philippines and of course the Caribbean – just to list a few. Truth is, I wouldn’t even know if I just covered all the continents cause I HATED geography!
