can someone please provide a link or any information regarding the two passport pictures required in the application. When i mailed in my application i did send 2 passport photos. I am helping my sis fill out the application but i want to make sure i don't miss any info before i mail it. I noticed USCIS did modify some of their questions slightly different from the original forms back in august of last year. any links to websites with guidelines and checklists will be much appreciated
