The decision is up to you, but ultimately you are closing one door and gaining the ability to vote and hold a Canadian passport. Nobody knows what the future holds, so I always say the more options / flexibility you have the better. Also, perhaps your children would want to study in Europe one day and having German citizenship would make it so much easier for them.I’m getting cold feet now!!! I’m getting closer to oath and I don’t really want to lose my German citizenship! But the “Beibehaltung” seems too hard to achieve. I’m not planning to ever move back but I feel like I’m losing my identity!!
