Hi, i am a bit confused with the updated UCI. previously, i applied for visitor visa, which got approved last year. thus in my ee profile, i added my UCI from the visit visa. today when i saw the update, i saw that now there is new UCI which starts from CANxxxxxxxxxxxx (12 digits) but when you click on the Help under Personal Details --> Immigration History & Citizenships, it only says 8 or 10 numbers. so my questions are, which UCI will i use now, the 10 digit from my visitor visa application, or this CAN + 12 digit number from EE. I thought from previous research, uci will not change.
Thanks for all who will answer.
