我需要FILE I-485A(也就是FILE 245(I)要填的一个表)。INSTRUCTION中说：要提供
“Documentation of your physical presence in the United States on December
21, 2000, can consist of federal, state or local government-issued documents
or other documents establishing your physical presence on that date. If
one document does not establish your physical presence, you should submit
documentation establishing your physical presence in the United States prior
to and after December 21, 2000. ”
我没有刚好12/21/00这一天的DOCUMENTS，请教高手：我应提供哪些DOCUMENTS来证
明我12/21/00前后在美国？这个12/21之前和之后的RANGE多长比较好？谢谢您的指
点和帮助！
