Hi, I'm applying online for citizenship under 3 year rule which means my husband is a USA Citizen and I can apply under 3 year rule. I'm married and I have two kids who live with me and my spouse. When I completed the application online, they asked me for the child and spousal support evidence. For an N-400, you may need to provide documents that show you support your dependent children and that you have complied with child support obligations. This can include: Canceled checks or money order receipts. A court or agency document showing child support payments. Evidence of wage garnishments A notarized letter from the parent or guardian who cares for your child(ren) A written document from the other parent stating the amount you have paid on a monthly basis. Because me and my spouse live and raising our children together the only evidence I can provide is A notarized letter from the parent or guardian who cares for your child(ren). Could you please write a letter for me stating the I live with my spouse and both of us support each other to raise our children. Then I will notarize it
