You need to be from one of the following counties to teach English in South Korea: United States, Canada, United Kingdom, Ireland, Australia, New Zealand, South Africa. If you are not from one of those countries, you can still teach English in most other countries. This requirement is specific to South Korea and school's can only issue visa's to teachers from those listed countries.

Due to the high number of applications the schools receive they may not be able to respond to every application. If you don't hear back from them within a week or so, it's best to move on to the next job.

When applying for jobs, you should NEVER have to pay to apply. You should also NEVER have to pay to buy anything which they then pay you back for later. NEVER PAY FOR ANYTHING! Also always verify you're actually talking to the company in the job post and not an imposter. Scams in TEFL are rampant, be careful!
