I am applying (Adjust. of Status; I-485) as a derivative applicant. My spouse has an approved I-140 (National Interest Waiver).
In the I-485 Instructions, page 10, section titled "Documentation of Your Immigrant Category", USCIS asks the derivative applicant (i.e, me) to provide a photocopy of 'the principal applicant’s petition'.
My question is what exactly should derivative applicant provide here?(i.e., how many pages of what?)
