Hey srikar,
good to hear your interview went off smoothly. At POE they don't ask for the Xray but you had better carry it just in case. I have never heard of them asking for it but it is safer to carry it. Th Xray from Breach candy was quite small and the envelope was bigger so I just folded the extra paper of the envelope and put it into my handluggage, along with the other papers. Bets of luck and congrats again.Enjoy your new status. I sure am!
