So I've been trying to do my due diligence in regards to applying for proof of citizenship. I've gathered Mine, my brother's, my dad's, my grandfather's, and my great grandfather's (the anchor) birth certificates. I also understand I should create a small family tree linking me to my anchor ancestor and include a cover letter. Other than that, I recently read that I need to pay the fees online and then include the receipt with our applications? Also, where did you guys go for the 2 photos? As I understand it, the dimensions are slightly different than US Passport photos. Do I need anything else? marriage records? various supporting documents? Any and all advice is welcome and appreciated!
