Though recruiters are a strict no-no I have seen a few good things said about this one.
My personal experience with this set-up is a big nought as they haven't even bothered to respond to my application. That, however, maybe the case because of rooted prejudices that seem to be getting more strongly entrenched of late. I'm not 'white' . (New Times, care to respond?)
Visas - I have never had problems getting my 'l' or tourist visas converted to 'z' visas and to that extent the claims made are right. At least, that's the situation if you're hired by a university.
Hope this helps.
Good luck with your job search!
