O Visa To Marraige Extension

[rabcbroon]

I intend yo apply for marraige extension as my multiple O is due to expire. Do children/child living at our address need to be entered on the blue book and do they have to attend the immigration office when application is made?

Also my visa is on the final 3 month period (12 to 15 months) and will expire 20th november. When would be the best time to make application. I have hear 1 month before it expires. Is this the best time or would it be better to allow a few days in hand for hick ups?

Thanks

Not sure on children if extension is for marriage. The month early is providing the extra time for any missing documents - do not believe they will want to process before the 21st of this month. I would go 28 or 29 - that will provide you plenty of time.
