Thanks, this is very helpful!

My wife will be renewing her passport following attendance of the seminar, so she will also be returning to the CFO office to get her sticker after her visa has been issued. From what other members have said, the sticker will only be given once the validity period of the visa begins.

I will make sure my wife has all of my details when she attends the seminar and be on hand over the phone if she needs to ask me anything else.
