I am trying to locate a Naturalization Certifcate for a family member. I thought I requested the right document from genealogy.uscis,dhs. But I only did an index search. When I go to request the it asks for a naturalization certification number. I thought this was the point to find it.
How do I request the document or how do I find the naturalization number? All I have is their name on it an an alien enemies # 3404-P-1730 and a date of 7-26-43 to go off of. I am trying to find out if they naturalized or not.
