Talk about desperate and ridiculous... check out this latest job post for Korea:

The first two schools state the starting date is next Monday, JULY 6!!!

I began the visa process the very same day as I was offered a position -- and it took two months!

They ask that the person be an E-2 visa holder, but that is also quite problematic because one needs to be "released" from the previous employer, which basically never happens because any teacher who resigns is not granted the release and is forced to leave Korea within a very short time. And if the FT has completed the contract, again, they have VERY little time to hang around Korea. Most leave within a few days of contract completion.

Obviously these schools have sold the classes to parents before securing a teacher. So typical.
