You can apply for a second passport for many different reasons. If your native country of citizenship is politically unstable or unsafe, you can choose to seek a more secure life for you and your family through your dual passport and stay for an unlimited time. For some minority groups, the second passport can also be a way of escaping prejudice and discrimination. Not only your children, but also generations to follow will obtain the same citizenship rights.
Other reasons for applying for a second passport could include the wish to establish a new business in a place without financial sanctions or restrictions. Your new passport can help you facilitate frequent international travel and provide more freedom. You will be able to own and register your assets internationally and can gain direct access to a bigger market and a greater customer base.
