I have questioned myself that as well. This whole online system is a mess!
I applied online January 17. I submitted a webform to update my expired healthcare with a new one and they told me they did not find anything application.
I called immigration and they said they did not find anything.
They asked me if I got an invitation and I said no. I used the link on your website.
First of all, how did those people got an invitation?
Also, they asked me if my application has a number and I was like, should I have an application number? and of course they are not sure.
If they don't want to accept any more. Should they just shut down the system??
