Generally speaking, long wait times are not the result of processing admissions. Long wait times are generated when the volume of applications received is larger than the targets we are permitted to issue. That is for the overwhelming majority of wait times at missions abroad.
It is certainly true that, in addition to that, a certain number of applications have fraudulent documentation on them and generate additional processing time, and particularly in the parents and grandparents category, medical complications, particularly active tuberculosis, can lead to significant processing times.
Those I think are the smaller element of processing delay, the larger one being the difference between application intake and these targets.
