The most recommended approach is to directly contact the Delhi University Admissions office and explain your situation.

Explain that your EWS certificate is under process and inquire about the possible alternatives for document submission on the CSAS portal. The admissions office might suggest uploading a copy of the application receipt you received for the EWS certificate, or they might provide an alternative document submission process.

Some institutions might allow uploading a provisional EWS certificate issued by the competent authority while your main certificate is being processed. It is crucial to confirm with the DU admissions office if they accept such provisional documents before uploading one.

If options 1 and 2 are not viable, you can still submit your application on the CSAS portal. In the designated section (if available) or as a separate document, clearly explain that your EWS certificate is under process and provide details like the expected issuance date (if known).
