Hi Wallajas,
Read all your thread and I assume they are going to announce the review before june 2018. But I have a feeling that they may bring the income requirements up a bit this time. (Time will tell)
Currently in same situation as yours. Looking to sponsor my father and was become eligible a month before they closed the category. Hopefully they come up with not too hard sponsorship requirements this time once they open the category. Is there anything else you know of about the coming changes or what do you think can happen?
I believe you may need to show your 3 years of income. but Immigration officer will tell you about this better once they open the EOI pool and send you the invitation. Have you applied your parents EOI already?
Looking forward to hear back from you.
