附上解释信。。想一开始就给vo合适吗？My name is xxx，passport number . During my last interview I was so nervous that I failed to answer the office’s questions well. I would like to elaborate on three points 1.(University) I am now a senior student of human resources management atxxxz), because my undergraduate school and profession are not good, so I have been reviewing graduate examinations over the past year and a half. In February 14 this year, I passed the xxxUniversity judicial master test, but the admission letter will be notified in mid-April, which enrollment number is fifty people, and now I ranked tenth (relevant proof can be provided). 2. (Purpose) My travel from April 20 to April 28, my boyfriend will to participate in the 2017 American xxxxSession from April 22 to 25,and he has got a B1/B2visa. In the past year , when he went to lectures, I will accompany him to travel in passing. We went to a lot of places of China, but because he used to be xxxx, and got a passport in February this year. So we failed to travel abroad. This trip is my graduation trip, because I will review the judicial exam in June. So this trip is really important to me (Itinerary can be provided). 3. (Family) My parents agree and will finance the main expenses of my trip, and they think that is a reward for graduate exam. I am the only child of my parents , and my mother has depression, so I will not stay illegally in the United States to let her worry(Bank deposits and Proof of real estate can be provided). Trust all above can be self-explanatory，I sincerely hope that you can consider my visa application again.
