Can a person exit Singapore with a Singapore passport and enter?
Singapore does not permit dual nationality, so you cannot hold a Singapore passport and one of another country, however it would be possible if you held say an Australian passport & a Canadian one, in this case you could depart Singapore on your Australian passport and enter Canada on your Canadian passport. Well actually, you would HAVE to use your Canadian passport to enter Canada (as a Canadian citizen you cannot enter Canada on any other passport)
