USCIS recently sent us a RFE asking for MMR vaccinations, as my wife didn't take this during the 140/485 applications 6 months ago, as our daugther was just 2 months old and was breastfeeding. She is still breasfeeding and we'd like to continue to do so until the baby is at least 18 months. If we have a doctor put a statement in the supplemental I-693 saying that "the mother is breastfeeding and will provide MMR in June 2008", will the INS keep my wife's application in suspension until we provide MMR results or will they issue greencard and ask for MMR in June 2008. Any inputs in this regard will be highly appreciated. Thanks in advance.
