@CaBeaverThis is insane. To submit your applications more than 25 business days, and then be charged express fees to expedite the process. I am afraid this will happen to me as I have travel plans in April. Anyway, since the supporting documents returned to you, it means your applications have been approved most likely, and passports are in printing. Why did you ask to transfer the applications? Do you have travel plans? Because I don't think they transfer files without a proof of travel soon, do they?
Do they return all the supporting documents or just the originals like Citizenship Certificate? Did you get yours already?
