My son and daughter are citizens of the country they were born in, but could choose to acquire citizenship of their mother's country of birth, by descent. For my daughter, this might be a nice-to-have as it would make things easier for her if she chose to reside there for any period of time. For my son, it's a more complex choice as he would be required to complete military service in that country. For some teenage boys that might be the adventure of a life time, for others it would be a nightmare. I'm planning to let him decide what he wants to do.
