I’ve got my Korean Driving license and its valid for 10 years. Yay……
If you have an alien card (staying longer than 90 days) you may change your home country’s driving license to a Korean one.
First, approach Road Transport Department (JPJ) only at Putrajaya or main braches of every state. Ask them for a ‘confirmation of driving license particular’.
Second, bring the confirmation (original + 1 copy) to the Malaysian Embassy in Seoul to get it notarize (purple box). Also bring along your Malaysian Driving License (original + 1 copy), Mykad and 6,000won. It will take 4 working days.
Lastly, proceed to the nearest Korea Road Traffic Authority with the notarized confirmation, passport (a valid one woth your date of entry stamped), Malaysia driving license, Alien card, 2 photos, and 12,500won (5,000won for eye test and 7,500won for license application).
Check the link above to find one nearest to you.
The road department will keep your Malaysian Driving License for 3 years and discard if not claimed. The only way you can claim your license is by showing a proof of returning to home country (flight ticket). You may then keep it.
