alright, i went to the office where i did the fingerprint this August. He told me if i am sure that i submitted the certificate this August i can just leave it alone. But i am afraid it may confuse the officer if i submit it again. Do you have an email that we can contact directly. Mine is lzy0846101@msn.cnlukeqichen said:No, I am not sure what I should do, I may do another check next Monday.
