I read that you guys mentioned about yellow book and 2 sealed envelopes, one of which is to be turned in for visa interview, and that the yellow book and the other sealed envelope is to be turned in later for AOS. But I just called the Health Care Center of Guangdong International Travel for the medical exam. They said they would do the vaccinations (4 shots) with the medical exam on the same day. The DS-3025 will be sealed in the envelope with the other papers which is to be turned in to the GZ consulate, and only a copy of the vaccination record will be given for us. Would we have any problems with this later for AOS? And by the way, would it be okay to get 4 shots in a day???? That sounds a lot!!! Thanks!!
