Dear student,

As you mentioned that you have your obc non creamy layer certificate but your annual income is 8L and above so let me tell you if you are making obc certificate it cannot be more than 8L.

So, as far as the correction window is concerned it's a bit difficult to say when it will it be opened and if they will allow you to edit the annual income. I would advise you to kindly contact the officials regarding this. If not able to contact then wait for the correction window to be opened.

If they found any discrepancy they will allow you to edit it.
