I applied for a visitor's visa in June 2022 to attend a conference in Canada. It was not until last month that I received biometric validity letter that indicates that my biometric data is valid for 10 years. I was later advised to track my application using the visa tracker. When I track, it indicates that my application is in progress, but they show a Visitor's Visa Document Number that starts with "E" and indicate an expiry date which is 3 days from the date that my passport will expire. Does this mean anything positive? Could it be provisional or the visa will be granted eventually?
