How did you come to lose Egyptian nationality?
Egyptian nationality is hard to lose. Taking another nationality without the Interior Ministry's permission does not end it, nor does naturalising with permission to keep it, nor living abroad. Pick the event you believe ended it.
I took another nationality but never gave up Egyptian I naturalised abroad with permission and gave up Egyptian I lost it as a child, through a parent I lost it by taking a foreign husband's nationality It was withdrawn or taken away by a government decision I renounced it as an adult, as a dual national from birth I lost it before 1975, for example on leaving Egypt It was my parent or grandparent who lost it, not me
