Tell recruiting as soon as the graduation change becomes reasonably likely. The earlier they know, the more options they have for adjusting a start date or class placement.

A delayed graduation can affect eligibility, onboarding and work authorization, so this is not something to hide until the last minute. At the same time, a scheduling change is not the same as withdrawing from the offer.

State the facts, the expected new graduation timing and what is still uncertain. Avoid over-explaining or promising a date you cannot yet confirm.

Ask what documentation or timing they need from you and keep them updated when the university confirms the final date. Keep a written record of the university confirmation so you can provide it quickly if recruiting needs formal proof of the revised graduation date. For more detail, see the guide to choosing between consulting offers.

Would recruiting usually move the start date, or could they ask you to join a later incoming class?
