Hello Aspirant,

Yes of course it will create problem during document verification because at the time of document verification any exam whether it is IBPS PO or any other you have to produce the valid documents and if your EWS certificate is expired in December than it will not be considered as valid certificate in February '21 so what I would recommend you is to apply for new certificate and you can get your new EWS certificate before February '21. So you can produce your new and valid EWS certificate for document verification other wise you will be considered under Unreserved/ General category from which you will not get any advantage of reservation even after belonging to EWS category.

For complete details about IBPS PO kindly check out the link given below :-

I hope this information helps you.

Good Luck!!
