I found some good informative posts in this forum, i hope some can answer my questions..

My current visa is PSW expiring at 10th of march, my employer wants to sponsor me and he filed a online application for license.
I have some general questions like what minimum salary should be having to get tier 2 general visa? I work as a IT engineer. Do my employer has to advertise for job before issuing CoS? If the certificate gets delayed, can i still stay in country beyond my visa expiry?
Thanks.
