如果你今年交485,两年后被审,十有八九是要有Medical Exam RFE了,那时候再打也 不迟,没必要现在去把疫苗重新打一遍。 Flu Shot是说Medical Exam在4-9月之间的,就不要求。这只合你什么时候做Medical Exam有关,和审查时间无关。 Q. When does the flu season start for purposes of the seasonal flu vaccine requirement? Since the seasonal flu vaccine is required, do I have to get the seasonal flu vaccine if it is not the flu season? A. For purposes of the immigration medical examination, the flu season starts on October 1 and ends on March 31 each year. If your immigration medical examination is during this period, you are required to have the seasonal flu vaccine. If you have an immigration medical examination completed between April 1 and September 30, when it is not the flu season for immigration purposes, you are not required to document that you have received the seasonal flu vaccine. http://www.uscis.gov/news/questions-and-answers/vaccination-req
