Hello Aspirant,

If you don't have your EWS certificate right now but you are sure that you will get it by the time of counselling or admission then you can fill up your JEE-Main 2021 Application form with an undertaking for EWS reservation but if you think that you might not get the valid EWS certificate by the time of admission then you should go ahead with General category because that undertaking will not be considered valid for admission.

Suppose you submitted your JEE-Main 2021 Application form with an undertaking for EWS reservation and unable to submit your certificate then your candidature might also get cancelled because of providing incorrect information and false claim of reservation, so make sure to think over it wisely and until and unless you are sure that you will get your certificate by the time of admission, don't go with EWS undertaking.

You can download the undertaking from the official portal of NTA, for which link is also given below :-

https://jeemain.nta.nic.in/webinfo2021/File/GetFile?FileId=5&LangId=P

When you visit on the above link you will find a PDF and on page no.9 there is undertaking format which you have to download and after filling it you have to upload it on the place of category certificate in the JEE-Main 2021 Application form.

I hope this information helps you.

Good Luck!!
