Im set to start on the 20th after being pushed back twice now. Tried to get some information out of my recruiters as to how certain the 20th start date is - they claim its more than likely but still not 100% certain. My advise would be to not put your life on hold while you wait for this because at the end of the day its down to immigration when we go as they have to sift through all these visas.
I have a friend teaching over there already and I know someone who left last weekend, they got their visas either 1/2 days before they actually left so it just requires a bit of patience from all of us. I'm sure everyone will get their tickets.
Again I have a group chat going with a couple of us from this forum post, Flomat19 along with others are messaging on there for updates as it's easier to communicate. If anyone wants to join drop me a message!
