Hi Marisawright
Thanks for the reply. When we left South Africa I had a letter from the then foreign minister that I could hold both South Africa and British passports, hence dual citizenship. If it has changed I do not know about it.
Regards the end date I have to fill in a date. We were thinking maybe use today's date and in the comments box below say we are still British citizens and just put that date in to complete the form. ???
Cheers
