先把他們信中的要求的材料補了。 等他們如果通知還要再提供一些其他的支持文件。我再補。行嗎?
-Because you have not provided your parents' marriage certificate yet, you may provide the evidences I suggested together with your parents' marriage certificate, if possible, because I am sure they will ask for these evidences later. Of course, if have no time to prepare these evidences before the RFE deadlines, you may just provide the marriage certificate first and wait for another RFE.
