I emigrated from South Africa in 1987 to Israel where I obtained Israeli citizenship by the Law of Return. I retained my South African citizenship by applying for and receiving a letter which allowed me to retain my SA citizenship. It was always clipped on the back of my Israeli passport. In 2001, I emigrated from Israel to Canada and obtained Canadian citizenship in 2005 - WITHOUT applying to retain my South African citizenship. I, therefore, now have dual Israeli and Canadian citizenship. My question is whether I am still regarded as a South African citizen by virtue of the Letter of Permission I received to retain my citizenship back in Israel ? - or is it now invalid because I didn't apply for new permission before acquiring Canadian citizenship ? I am guessing that I am no longer a South African citizen. I am traveling to SA for a visit in 2012 and don't want to have problems when trying to enter and leave South Africa because my SA passport expired in 2007. I don't want to renew it or get a new one. Will it show up on the computer that I have an expired SA passport ? - or did the passport become invalid when I acquired Canadian citizenship ?
