Registering for CFO. We have to enter the visa number. Usually a diagonal line through the character means its the number zero. However, other characters other places within the visa are clearly number zeros but they don't use the diagonal line. This is stupid. Look at the issue date and expiration date, clearly those must be number zeros in the issue date and expiration date. Even in the control number itself, the first 4 characters must be all numbers to indicate year 2025, and yet there are no diagonal lines through them.
