yea, esl teachers often need a work visa depending on the country, but schools generally sponsor your visa if they hire you, so that's all taken care of by the school staff or they'll walk you through the process. if a school doesn't offer to sponsor your visa, they're not worth the trouble.

it was awwwesome and i got to retire very early, so it's tough to complain about anything.

Really there were no challenges with the job itself, speaking basic english and playing learning activities with a bunch of respectful, dedicated, cute students for 45 minutes at a time(including a 10-minute break), watching them improve and leaps and bounds evey week, get paid USD $35 per class minimum. Rent/food/everything pennies on the dollar. My most expensive apartment was about three hundred and fifty U.S. dollars right in the middle of Beijing, but the studio I rented the longest was $120 a month. 4 classes and my monthly rent and utilities were paid for.

the only challenges were with other administrators after i ended up co-owning the school that hired me, they were pretty bad at business and it was frustrating to see this extremely successful business that was fun to work at run so poorly.

oh, i was in beijing, so the smog was the other main challenge, but it's such a comfortable and convenient country to live in, I still ended up staying there very happily almost six years altogether, and have great friends that I still talk to and actually just visited last month.

Wayyy more ups and downs.

there are tons of chinese cities that aren't smoggy, but Beijing was where I started and that was my journey.
