H4 221g white slip

Hello… I need help… I recently got married and my spouse appeared for H4 visa interview for her first stamping at Delhi location on August 16th 2018 and she was given 221g white slip asking to mail primary occupant visa copy, marriage certificate and marriage photographs. Her passport was also returned.

She was carrying all the documents mentioned as part of form 221g, and it seems officer wanted to see more photographs.

I returned to US last week only as I got my stamping done in drop box.

Did anyone face this situation ever and what are the odds of getting the visa? How long it takes to receive response after mailing the documents?

Did she get the visa??
