Hi i have just spent the last 6 months working on a 411 vias in Australia,i went out there a single man but now i have a girlfriend she is a Australian and we have been together since December i'm now back in the uk and she is due to come to visit this summer. I am 36 years old and have used my working holiday visa long ago.We plan to go back to together in October,which visa will give me a good length of time so that i can work and we can be together without any hassels when i return.
Any ideas???
