Understand decisions you've had to make around this. In my situation, I applied for a 1 year work visa just because I wasn't sure how long it'd take to process a SMC residency. I've just applied for residency, and all is looking ok so just waiting now. I wasn't sure how long I'll be here either, but you never know if they'll change the residency requirements and then it be even more difficult to get in. So I thought best to put it in now before it changes! EG. citizen requirements changed where you only had to be in country for 3 years to apply (back in 2005) and then it changed to 5 years. So quite a significant change.
Now after being here just a few weeks, and starting a great job, I am falling in love with the country! I can totally seeing me staying here longer term. :-)
