Switching from hagwon to public school: visa question!

Hi!
I'm going to be making the switch in September from a hagwon to a public elementary school - will I have to get a new visa? Or can I just extend my current visa?

You can extend and the public school will accept documentation from immigration showing that your degree and criminal background check are on file.    But you will need to provide them with new - original, sealed transcripts. 

They'll accept proof that your BA is on file but not proof that your transcripts are on file.  You need to get new ones.

I can confirm. I did this last year.

I did the same thing in March. Just had to get a hold of some new transcripts. Everything else they had on file. Got my Visa changed over to the public school and was done. No hassle, except the Immigration office, but that is to be expected.

Did you not have to get a new CBC? I thought they are only good for so long.

A new native country Criminal Background Check would only confirm that you've not been convicted of any crimes in your home country while you haven't been in your home country.   The Koreans are (perhaps surprisingly) sufficiently wise to recognize this and thus have not requested additional Criminal Background Checks thus far. 

Just bumping this topic.

Can anyone confirm this information is still true? I may be in the same boat when my current contract with my hagwon is up!
