This material is a Petition for writ of Mandamus to compel the USCIS to act over your case and instructions to it. You may use it as a basis or example of composing your own Petition if you are unrepresented by the attorney litigant. 
 
I highlighted in yellow everything you need to carefully replace with your personal dates and circumstances. The Point titled “Introduction” is highlighted entirely because everyone has his or her own circumstances and description of what has happened to his case in general.
 
All legal stuff such as authorities, conclusions, citations, and federal statutes comprise the legal arguments supporting your claim only if your case is before the USCIS.
