As a teacher I came under the skilled migrant category
hardest thing was although I got job offer in November the job started in Feb I was granted the work visa a few days before the job started
Immi CO rang me and said that I had applied 'too early' (Nov)
I explained that the Principal needed to know before the end of Dec Term that I was definately going to be available to start work in Feb
my CO rang the Principal and explained that I would get a work visa...just not until Feb!
All worked out in the end
