之前收到了UIUC的AD,随机预约了5月3日签证,向他咨询I-20什么时候发过来,他这样回信: Your I-20 cannot be generated until your sevis record is sent to the U of I (generally around or after the time of graduation). Please check with your school regarding the time they release the records. 意思是要先交SEVIS费用再发I-20过来吗?是不是我交了,record是不是马上就能发到学校那边了?这样的话不知道来不来的及5月3日签证啊。。。
