I'm guessing you have had sponsor approval already? If so, you could have applied for the OWP when that came in.
What are you from? This is just out of curiosity as you say you're on your 4th IEC and didn't know you could have that many.. 2 of 2 years I'm guessing?
Yeah i am australia who applied pre march 2015, got 2 of 2 years yes.
I didn't even know there was a "Sponsor approval" letter already. I would assume i already have it considering i have already gone thru medical and all that.
So if i have that i can apply for OWP. I read somewhere that you can get "implied status" if that is the case...
