My wife is qualified to apply for citizenship. However the first 1.5 years she was a homemaker and also since she moved from the Gulf, we did not know anything about dependent visa cancellation at that time and her residence permit is also non-cancelled. We use to live with our parents as a joint family, so we didn't have a lot of obligations of things needs to be closed in the country before leaving. What proof of residence can be used in her case?
