No. CICD may make a minor adjustment to the start and/or end dates on your DS-2019 Form to indicate your actual date of arrival (for example, moving both the start and end dates two days earlier or one day later) only if those dates correspond to the official vacation dates of your university in your country, and only if the total adjusted time is not more than four (4) months total. Certain countries require students to return to their home country and school by a specified date. Over staying that date can jeopardize offending an student’s immigration status and/or chance to return to the US as a tourist, on another visa or to repeat as a J-1 SWT student. Check with your SPONSOR to make sure whether any required return dates apply to you.
