Baby born after the interview


My son was born after issuance of the visa and i went with him to activate my visa in august. At the POE we were asked for his passport,2 photos,birth certificate- english version (they took the orig from us),and vaccination card. There was an argument amongst themselves about medical exam from a doctor here but i showed them an email replied from abu dhabi embassy. Finally after 2hrs of checking and verifying details, he was admitted with the passport stamped XN-3 and they promised the green card will come along with our cards. What is surprising is we have never received it despite all our cards being delivered after 3weeks. Does anybody know how we can follow up on his card?
Hi did u get the green card for ur child?
