Hi,

If you have rectified the defects and uploaded the photo according to the specifications you need not worry, It takes time for the status to change. You application will be reviewed and accepted if the photo is rectified are as per the specifications. The process takes time as there are lakhs of applicants  for GATE 2022. Your application won't be rejected, if there are any changes to be made still, you will be informed through your registered E-mail ID.  So check your registered E-mail ID from time to time.

You may also send the authorities an e-mail for confirmation if your photo has been uploaded or not.

In case, if any of the above situations are not applicable. I would recommend you to contact the authorities directly through mail or phone. You can find the details for the same here:
