Moving to Korea to directly look for university positions: good idea?

I am not quite there yet, meaning I am not fully intent on doing so but I am considering it, say for next year depending on how things economically work out for me here; is this a good thing to do as a rule? Perhaps combine it with a Korean language course? I realise that most universities do not interview over the phone and only an in-person interview would be acceptable and I have read several things online that suggest doing this. What would the experts' opinion be here? I think inevitable in some sense that I have to return to Korea anyway so planning at this stage is not a bad thing. Cheers!

Re: Moving to Korea to directly look for university ...

they want someone on land. so being here is crucial. they don't want to pay more than they have to. visa runs to japan are easier for them, if they pay for it at all. and despite being advertised on sites like this, they tend to do word of mouth hiring more than ads on the internet. you'd have to get to know someone local first. these jobs are coveted by a small number who do what they need to to avoid public school and hagwons.
