We got an update stating that CIC would request for passports only after the US-Canada travel ban is lifted and asked us to contact us after. If anyone got some other update, please share.
CIC responded back saying that there should have been some other documents along with the passports for me when they did not send anything else. Raised another webform mentioning that they did not send anything else.
@Rangrez I am in the same boat. Our passports were delivered on March 17th and we got it back with nothing. They returned the passports and photographs. My guess is its because our medicals expired last week.
