Thanks for replying.Hi,
I am very sorry to hear that. Can you please clarify, when did your parents receive the permanent resident application.
As per the temporary public policy, if your parents received PR application on and after 16 April 2018, then it will be treated under new policy. refer to temporary public policy here - https://www.canada.ca/en/immigration-refugees-citizenship/corporate/mandate/policies-operational-instructions-agreements/excessive-demand-june-2018.html
Also the fairness letter would list many more details, which will tell you whether the application was considered under new norms or the old one. If the application was received before the Apr 16, and if the listed medical facts doesn't pump up the health related expenses (as listed in fairness letter) more than 19K, the solution would be to reapply for PR.
Thank you.
PR application received in 2017, but still under process. But the fairness letter we got is mentioning the visitor extension so I guess right now they are worried about visitor extension.
For PR they just got request to do some more tests.
