485 RFE 求助: 怎样证明离开美国的出境日期?

485 RFE 要求如下:
Therefore, you must submit evidence that you have resided and been physically present in the country of your nationality or last residence as indicated on your Form IAP 66/DS-2019 for an aggregate of at least two years following your departure from the United States. Such evidence must include stamped passport pages that document your departure from the United States upon the completion of your J-1 program.

现有的中国护照上只有进入美国时, 美国海关盖的章. 没有出关时的章. 有中国海关的中文印章, 标明离开和返回的日期.

问题:
怎样回复RFE的要求? 难道中国海关的中文stamped passport pages 不能作为证据吗? 是否需要翻译公证这个中文护照页? 或者有别的方法证明离境时间吗?

多谢高手相助!

现有的律师似乎不了解J1签证的要求. 已造成485 RFE. 他认为中国海关的证据不能令人信服, 我实在很难相信他的判断. 但因为是雇主指定的律师, 似乎也不能换人, 烦请各位高人指点一二. 不胜感谢!
