When can I expect my passport back?

The consulate emailed me to submit my passport. I submitted my passport on the same day. I email the consulate on the same day of submitting passport and they told me that they are ready to issue the visa. But it has been more than 9 days and have not received my passport back. I email the consulate again and was told that my process is in the final stages and will let you know when your passport is read to pick up. Do I need to worry? as it has been almost 9 days that I haven’t received my passport?

What extra process they could be doing once they have decided to issue Visa?

Dont worry, you should be fine, you will get the passport very soon.
