J2 转 F1 USCIS要求补充材料（声明+证据）

大家好：


我目前的身份是J2，正在办理J2转F1，人已经在美国，目前USCIS的打指纹已经过了，之后收到了要求补充材料，其中一条是：“提交一份声明和证据，详细说明您在美国的长期逗留将对您的外国居留产生的影响。”

原文为：
Submit documentation to establish that you have maintained a foreign residence to which you intend
to return at the expiration of your period of authorized study. The evidence may include, but is not
limited to:
Recent telephone bills and/or utility bills at your place of foreign residence;
Residence Permit (government issued identity card) establishing foreign residence;
Letter from government authorities on official letterhead with government seal showing your
foreign residence;
A letter from your parents indicating that you reside with them;
Mortgage statements or current rental agreements relating to your foreign residence, to include
rental receipts;
A letter from your foreign bank, on the bank’s letterhead with the bank’s certification signature,
which verifies your foreign residence address, bank account number, and shows an established
relationship with the bank (e.g., bank account opened for 3 months)
In addition, submit a statement and evidence detailing the effect your extended stay in the United
States will have on your foreign residence.
This request for evidence pertains to your residence outside of the United States and not your
temporary residence in the United States, and USCIS will consider how much weight to give to the
evidence depending on all the circumstances/facts presented.

我想问的是：
（1）：这个声明要从什么角度去写？
（2）：要提供那些方面的证据？

感谢大家，请帮帮我！

蹲个后续～～～
