2021年12月初交了DIY 485，同时在485表的最后一页以additional information简短解
释了以前DY情况（来美10年了），这两天收到RFE，上面要求提供 sworn affidavit 来
说明DY情况 （如下英文原文）。
请问大家这个的情况应该怎么处理？是不是以前解释不够？sworn affidavit具体指什
么？ 需要其他的附加证明材料嘛？希望有经验的XDJM帮忙指点！拜谢！
"Please provide a sworn affidavit regarding your membership in a XXX party
as you stated on your I-485. The affidavit needs to include the following
information. What was the name of the party? Why did you join party? When
were you a member of the party? Was your membership voluntary. Did you have
to pay any money for being a member? Are you still a member of a XXX party,
if not what is the date your membership end?"
