Just want to drop a note on getting a Korean work visa.
I had been looking at the g4f website to see which visa I could get depending on the job I get (assuming I get a job); and to actually see if I could get a visa.
Then as I could not find a few specific information about E-7 and E-8 visas, I called the Korean Embassy in Belgium and they said that usually, no matter what, if I get a job in Korea, I will get a visa.
So they told me that when I get a job, I just have to give them a call, tell them what kind of job I got and they would try to make me fit into one of the numerous categories*.
Bottomline is: focus on getting a job, and don't worry about the visa stuff.
* C-4, D-7, D-8, E-1, E-2, E-3, E-4, E-5, E-6, E-7, E-8, E-9, E-10, F-2, F-4, F-5, H-1, H-2, and a few others were employment is permitted as a non primary activity...
