A typical complex situation and I wish this would not happen again with anyone.
1) What's the status of your Renewal or reissue of Indian passport? Did you check ✔ online???
2) What's the status of your citizenship application? Did you get AOR ?
Until I do futher research on your situation.... I would answer it in general
