FSW-O applicants can call them as well, at least from the US. That said, it doesn't help much and they don't provide any information on when folks like us will be released from the backlog and processed.
I have sort of accepted that we're a low priority for IRCC.
Especially with the recent announcement that IRCC will take new applications from temporary workers and international students already in Canada "to meet immigration goals", the future for the 2019 FSW folks, inland or outland, is NOT bright.
I am sooo tired of having my life on hold because of it all. So tired. I still hope to start my life in Canada, but this whole Express Entry system is a prime example of "overpromise, underdeliver" approach.
They promise a lot, and they simply fail to deliver on their promise.
