Reason of delay
There is a cut-off date and all the pkt-3 received before that cut-off date are considered for next interview schedule. For example, Say New Delhi\'s cutoff date is last day of every month. So if your pkt-3 is received and enetred on 30th January, it will be considered for the list to be declared on Feb 15 and you may get a date from March 10 to April 10. Say you got March 10. It is about 40-45 Days.
Now, say your pkt-3 was eneterd by your consulate on 1st Feb. It won\'t be considered for the Feb list but shall be considered for March list(to be declared on March 15) and you may get a date from April 10 to May 10. Say you got May 10. It is about 90-100 days.
So, Best timing: 40-45 days
Worst timing: 90-100 days.
Poor me. It took 90 days for me and so know this fact.
