请问8老师，
我在帮父母申请绿卡的时候，一起file i-131 for ap。
131表上说. on a separate sheet of paper, explain how you qualify for an
advance parole document, and what circumstances warrant issuance of advance
parole.
后来查了instruction,
you must attach:
1. a copy of any document issued to you by USCIS showing your present status
; and
2. an explanation or other evidence showing the circumstances that warrant
issuance of an advance parole document; OR
3. if you are an applicant for adjustment of status, a copy of a USCIS
receipt as evidence that you filed the adjustment application;
那和485一起申请，是不是不需要An explanation letter showing the circumstances that warrant issuance of an Advance Parole？
多谢8老师！
