父母马上就要到广州做移民面试了。在使馆寄来的信中要求带的资料中，其中有一件是父母的结婚公证书，但是NVC要的可以是original or certified copy, 我已经把original marriage certificate 寄给了NVC。所以我们没有结婚公证书。这会不会是个问题？
-No problem. Just bring a copy of that document and tell the IO tha original marriage certificate 寄给了NVC. Actually NVC has sent all your father' case documents to the US Consulate incluing your parents' origianl marriage certificate.
第二个问题是使馆要“美国申请人从美国汇款给申请人的汇款单”。我汇款都是用支票的，所以没有汇款单怎么办呢
-If you not have, just ignore it. You may just providehe cleared copies of your personal checks you sent to your parents from your bank account statements.
第三个问题，“现时工作证明”----用什么证明？
-If your parents have no job (retired), ignore it.
