Sneha B posted a topic in Application ProcessI am applying for Citizenship-form N-400 (I am filling in the N-400 online) as I have completed 5 years as a Perm Resident. The form requires me to provide details of my children and asks for their Green Card A number. Both my children are already US citizens so technically their Alien number on the GC should be 'invalid'. There is an option to check the box that says- "Does not have an A number". Should I check this box and not provide a Alien number or should I provide it though they are citizens.? Similarly the form asks for my parents' citizenship status. My mother is a US citizen. The form asks for her naturalization date And then goes on to ask what her GC Alien number is. Again should i provide an "A" number or check the box that says "My mother does not have a A number"
