Finally getting into the 21 century! Ya things seems to be getting a bit better —hate to say it but the only good thing g about COVID has been is push some updating
well the USA situation being what it was and my passport expiring in August I sent it last month and took a week—but as to the question—how long is the window to transfer the visa —thanks
Ages ago I also lost the slip while doing my extension and I was at CW, they hassled me to know which airline and day I flew and magically after paying the fine they showed me a print out of the information. Give it a try and since CW is not so busy I’m sure they can do it quick.
I went at 9:30 am a few weeks ago and took under 30 minutes. They have a QR code that lets u know ur queue in real time. Was impressed at the speed and staff was super polite and friendly.
