My friend received a procedural fairness letter after his visa was issued, but he wasn't aware of it. When he tried to board the flight, he was denied boarding and informed that his visa had been canceled due to an alleged issue with his bank statement, which was untrue. We resubmitted the bank statement along with an explanation letter. Now, two weeks later, there's another update in the portal mentioning "biometrics validity confirmation." We're unsure of its significance; does it imply the visa has been revalidated? Could you please help us in understanding this?
