Applications for a work visa can be made inside Korea, but you must leave the country to pick up the visa. Most applicants fly (or take the Busan ferry) to Fukuoka in Japan, where it usually takes two days to process the visa. You can also apply for a one-year work visa before entering Korea but it can take a few weeks to process. Note that the visa authorities will want to see originals (not photocopies) of your educational qualifications. This a safeguard against fake degree certificates.
You don’t need to leave Korea to renew a work visa as long as you carry on working for the same employer. But if you change employers you must normally apply for a new visa and pick it up outside Korea.
If you don’t want to forfeit your work or study visa, you must apply at your local immigration office for a re-entry permit before making any trips outside South Korea. The fee is W30, 000 for a single re-entry or W50, 000 for multiple re-entry, but permits are free for some nationalities.
If you are working or studying in Korea on a long-term visa, it is necessary to apply for an alien registration card within 90 days of arrival, which costs W10, 000. This is done at your local immigration office.
