Ark Academy students demanded lower fees on applications for British citizenship at a rally at the Home Office on National Poetry Day 2018.
The students say the £1,012 fee for a child's application includes £700 profit for the Home Office. There is no consideration of an applicant's income, and no refund if the bid is rejected.
"This requires a sense of urgency," Ark Academy student Hadeal Abdelatti, 15, told a crowd of 160 protesters. "People cannot claim an identity which is rightfully theirs."
The Home Office has commissioned a review of fees. The review is expected by December, but any change would require government approval.
Citizens UK coordinator Tahmid Islam said: "This affects 120,000 children across the UK. They have a sense of power about this."
