I feel your worry, I am just about to submit my skills assessment for my nominated occupation as a sports centre manager. My worry is the next stage which is submitting the EOI to skillselect. Not sure how long the EOI takes but once I get an invite to submit the visa application, you only get 60 days before that invite becomes void, I think you get a second chance before its taken off the system but I also have to give a 12 month job offer at that time. Its been stressing me out big time!! Its so difficult trying to get someone to give you that commitment. I have been pulling my hair out thinking about how difficult its going to be.
