I have never had that problem but my wife, who married me in 1963, had her citizenship taken from her in 2005 and we had to fight her case in the Courts for two years before her status as a Citizen was restored. My son had so much trouble with the passport office that he eventually used the links to Ireland – through my great grandfather, to get an Irish Passport, a process which was completed over the Fax system without problem.
The reason for all this nonsense was a desire by the Zimbabwe government to deny anyone with foreign links the right to hold Zimbabwe Citizenship and therefore be able to vote. It not only affects white Africans like us, but many Africans who have links to other African States. The numbers affected are staggering – one third of all young Zimbabweans have no birth certificates and cannot get a passport or vote despite the fact that the new Constitution specifically sets out criteria for citizenship by birth or residence.
