For those who have been applying unsuccessfully for years, here is my story.
I was gathering docs to apply when conservative government suddenly stopped the parents category program in 2011. When it was re-opened my income was not enough to sponsor. Could not apply in 2015 and 2016.
Finally my income improved and I applied in 2017 but did not get through.
Applied again in 2018, no luck.
Applied in 2019, the form just didn't open.
No luck again in 2020.
It has been extremely frustrating to see newer applicants to come apply and get through while I have been waiting for almost 10 years! yes, 10 years! I do not wish this on anybody, its a painful and hopeless process.
Now keeping my fingers crossed this time. Hopefully I will receive that email sometime over next few days.
