Hi top_secret again thank you so much fir your input.Yes my son have and showed the Cenomar and NBI at the interview.It was given back to him and was instructed to submit it together with his passport thru LBC. The reason I am confuse because the 221g letter is not clear.If we just need to download the required docs marriage cert and termination of marriages which the CO even explain to him to go to Ceac and submit it. And told him to sent the passport and original cenomar and nbi thru LBC .My son is IR2 visa.I guess its safer if we also submit the Marriage cert and termination of marriages thru LBS even we have downloaded it in ceac as instructed.Anybody have same situation as ours? Thank you so much
