How do I change my AT start or end date?

If a student needs to change their authorized J-1 Academic Training start date, they must contact their ISO Advisor and submit a new full request for Academic Training authorization. A new authorization must be completed, and Form DS-2019 and authorization letter be issued, before a student may begin their training/employment under Academic Training. 

If there is not a change in start date, but a desired change in end date of the Academic Training authorization, a full new request for Academic Training authorization for the extended period must be submitted and approved before the initial end date, the extended training period must meet eligibility requirements, and a new authorization be issued (Form DS-2019 and authorization letter).
