The delays, in those missions registering the largest number of them, are due to the backlog. These posts receive many more applications and these applications remain in the basket until they become files to be processed.
It is true that it can take much more time because we are waiting longer. In the end, what we see is that when a file is being processed, for example in New Delhi, it is probably dealt with as quickly if not more quickly than in the majority of our posts.
The problem is the time is takes before a file begins to get looked at.
