Documents for E-2 Visa
This is the basic work visa in Korea and the rules regarding required documents seem to change yearly. Also know that some of the materials you will be collecting take as long as 3 months, so prepare early before you come to Korea. Don't make the mistake of coming here first with the hope of finding work without all of your documents. It won't work. Most people find a position by contacting recruiters before they arrive. The recruiter will assist you in gathering your necessary documents. Then you will have to go to a Korean Embassy in your country to apply for the visa. It usually takes 2-3 days, so plan to go back 2-3 days later to pick up your passport with the visa. Here's a quick list of what you will need:
BA and MA Diploma (notarized copy only)
A clear copy of Passport (Photo page only)
