May I ask if the red circle in the picture indicates that the information needs to be filled in for children who are accompanied by others ?

Do you have a passport? Children with passports only need to fill out one form, while children without passports need to fill out two forms. My son is 6 years old and has an ID card and a passport. He needs his own separate form. Don't forget to get the exit and entry form for your child.

Now everyone gets a passport, just like a child, so this column is empty. Children and adults are exactly the same, except that when passing through customs, adults accompany children.
