Hello Divya...

In Josaa counselling at the time of reporting, document verification they're not asking you to keep exactly the same photo that you've in your jee main registration form , but you shouldn't change your appearance in the photo that you  have recently.

They ask for the photo in which you look similar (same appearance ) as in your previous photo in JEE main registration as it'll be easy for them to match.

Thanks...

All the best for your participation in Josaa counselling...

I hope it'll be helpful..
