HI All, I sent my daughters passports by Post in tatkal, and they were returned back in a weeks' time due to incorrect application. It was my mistake; I chose the wrong jurisdiction.
I resent the corrected application as soon as I received the passports back. The timeline is as below.
February 5 - Pick up by purolator
February 6 - Delivered to BLS per purolator tracking
February 8 - BLS acknowledges reciept of application
February 9 - In transit from BLS to consulate
February 12 - Processing at consulate
February 13 - In transit from Consulate to BLS
February 14 - Passports received at BLS
February 15 - Passports delivered to my home
Conclusion : As long as your application is complete & correct, the processing is pretty efficient. tatkal took a total of 10 days including the postal time which is pretty good.
Happy to answer any questions to assist anyone.
