10. Frequently Asked Questions {#section-10}
Q. Is a university degree required for an E-4 visa? A. Not necessarily. E-4 values demonstrated practical expertise in the relevant technology field more than academic credentials. Sufficient industry experience and technical qualifications can substitute for formal education.
Q. Can I provide technology guidance to multiple companies on E-4? A. In principle, no. E-4 permits technology guidance only for the specific contracted company. Activities for other companies require a separate contract amendment or status change.
Q. If my technology guidance contract is only 3 months, will my visa also be 3 months? A. The stay period generally follows the contract duration. For short-term guidance work under 90 days, a short-term C-3 visa may be considered instead. E-4 is typically appropriate for contracts exceeding 3 months.
Q. If I receive a permanent employment offer from a Korean company while on E-4, what should I do? A. Transitioning to a regular employment contract requires changing your status to E-7 or another appropriate work visa. Technology guidance contracts and employment contracts are treated as different visa categories.
Q. Can I bring my family to Korea on E-4? A. Yes — the spouse and minor children of an E-4 holder can live in Korea on an F-3 (Accompanying Person) visa.
