us f1visa appointment slot i could find was 2 months after my class start date. i requested expedited appointment but consular replied me that they couldn’t do it. i then requested the university for Deferment and they allowed deferment and sent me updated i20 form that has different class date. since i updated my ds-160 with newer class start date i am thinking to Update Information at the Interview bringing both the old and new DS-160 confirmation pages and explain the changes to the consular officer. what do you suggest?
