A few years ago, I made the question. This focused on going out. However, I have doubts when returning to home country.
I will be flying with a family member, who is a minor. I know I need a written consent from the parents. That's fine. But, my doubt is when returning to the home country. Do I need any authorization? I guess not, since the minor and I will be returning. Still, I would like to be sure. Is there a common rule, or would this change from country to country?
