Regular appointment Visa stamping time / time taken for passport collection


I have my VAC and regular in-person appointment in Hyderabad in first week of August for my F1-visa. How long does it take for visa to be stamped and the passport be ready for collection?

I currently work overseas and will be flying to HYD for the visa appointment. Once approved I will have to put in my 2 week notice and go back to work for those 2 weeks. My fear is that I will be stuck in India if I cannot collect my passport quickly. Moreover the program start date for the masters program I’m admitted to is Sep 8.

I’d appreciate if anyone, who has recently gone through a first time regular F1-visa consular appointment (not dropbox), can share their experience regarding the time it takes before the passport can be collected.
