Is there any provision to provide reference to the paper which is in process to get published in journal at the time of graduate applications?
In general, the answer would be no since different conferences have different procedures. For the one of interest to you they may have something such as pre-publishing to aRxiv or similar. This is appropriate for your CV: ... &quot;to appear&quot;.
But you can also just say that your paper has been accepted to the conference that will be held on date future. You can also send them a copy of the paper if you like and they will accept it. And you can offer to send it in any case.
