Manav, the correction window is the last chance for you to make corrections to your NEET application form. Once the Correction window has been closed, you cannot make any corrections to it. NTA mentioned in its Information Bulletin that it neither entertains the requests to make changes in its application form nor does it make any changes on its own. Going by that,if you have selected EWS as your Category during filling the application form but do not have the document ready atleast for Counselling or document verification, you will not be considered under General Category. Your admission will stand cancelled.

Hello dear student,

if you are not able to to show your certificate at the time of counseling at the time of document verification then it is a problem. As it is there in information bulliten by NTA that NTA don't accept the request to change the information one chance is given to the students when correction window is open for the students to correct the information. But after that you cannot. and as you said if you are not able to show your EWS category certificate then you might not be considered under general category also your admission can be cancelled.

Thank you
