interview went smooth for f2a child of lpr but mistake on passport

[kingjb 1]

so my brother inlaw had his interview done at us embassy in islamabad case is under f2a minor child of lpr the interview was short and simple. how ever they pointed out a mistake where the passport and the birth certificate showed different place of birth location so they did not issue the visa officer told him to fix the place of birth in the passport so it matches the birth certificate and send us the corrected passport with the birth certificate to issue the visa. we already got the passport corrected and should receive the new passport next week one question is do we send the original birth certificate with the passport or just a copy please advise. also he was told to upload the latest w2 for joint sponsor through ceac we have already uploaded the w2s will automatically know that we uploaded it or do we have to sent an email or something to let them know we uploaded the document to ceac. thanks in advance
