Korea is one of the easiest countries to get around in, YES, even as a foreigner.

“Footprints Recruiting provided me with generous support in securing teaching employment in Taiwan. As a new comer to Taichung, Taiwan, Footprints staff were very accommodating in aiding my transition between Aussie living to Taiwanese living! The organization provided advice and support, and offered a position that suited me. Footprints also helped by providing support with travel/visa logistics, which was a great help. There is enough to think about when packing off to a new country, let alone what happens when you arrive. I was picked up at the airport and taken to a school which has great resources. I am pleased to have worked with Footprints.
