How do I change my OPT start or end date?

How do I change my OPT start or end date?

Once an OPT application has been filed, it is not possible to request a change in the requested OPT dates with USCIS. If the application has been filed, but not yet been approved by USCIS, it may be feasible to request to USCIS to have the initial application be withdrawn and then start from the beginning to request a new Form I-20 with new OPT recommendation and file a new OPT application (with fee) to USCIS.

If the OPT application has already been approved, then it is not possible to change the OPT dates that have been authorized. 

If you have concerns about your OPT application, please contact your ISO Advisor
