I actually went to the airport branch to obtain the visa in the first place. My experience was obviously not as pleasant as yours. I accept that I will need to return there to obtain a new visa. But to add to the twist, her visa expires 1 day before she flies! I would be far too nervous to apply for another tourist visa 1 day before she flies. I would prefer to cancel the current visa and purchase a new one.
Need more ideas QL? Can I simply cancel the visa now?
