To me, the difference would be to not target a specific group, such as adopted persons, adopted children. It would be really important to leave out the targeting of a specific group when you're discussing citizenship, because that automatically sets up a process that's discriminatory. Under the new rules that were introduced in April, when you look through the rules there's actually a title “adopted persons”. In other words, it only applies to this specific group, not to any other group.
That would be my suggestion.
