Hello

If you have obtained a migration certificate from Cluster University of Jammu, it means you officially intended to leave that university.

However, you can still seek re-admission, but it depends on the university’s policies and approval from the administration. You will likely need to submit a written request explaining your reason for wanting to return.

The university may ask for the original migration certificate back or a declaration that you didn't take admission elsewhere.

Since you mentioned not being admitted to the new university, it strengthens your case. Contact the university's admissions or registrar's office immediately for official guidance
