Thank you both for the advice, makes things a bit clearer, bit worrying that you can be caught out by an employer not doing PR even if they say they will after a couple of years. We also have to think about the fact we have a 17yr old that is going to want to do an apprenticeship out there and I imagine that would be a real problem if we are only on a temporary visa. I didn't realise the visa is tied to the employer and it is only them that can apply for the PR sponsorship, I had thought that after two years, we would be able to apply for the permanent visa. Thanks for letting me know about this, I assume it would apply to a regional sponsored visa as well and we would be in the hands of the employer again as to whether they were willing to go forward with a permanent visa, shame. Thank you both for the replies
