I finished the form, and I have some questions. What do they basically do to check my background? I'm just quite curious. (Worst thing I did was have disciplinary issue once in high school, which was listed in my application and passed). Do they call up the people I listed on the contacts? They're my close friends pretty much and my "aunt"(mom's best friend) Will my parents not being U.S. Citizenship negatively impact me? both of my 2 siblings have been naturalized.
