The methodology is based on:<br />- The number of applications each year<br />- The number of rejections that same year<br />- Types of application processes and their average processing time <br />The time period of each application process is assessed based on average duration and cannot exceed the 12 months. This meant the if an average application takes 220 days to process, and the application is granted. The ministry of social affairs calculates the remaining days up to 365 days (12-month rule .) into ODA calculations. <br />Once the application is rejected, the Directorate of Immigration assesses the time an applicant is in the country and calculates an average. For 2018, the average time until departure was 62 days before the applicants return to their country of origin. This cost was deducted from the calculations. <br />The average time spent on an application is used as basis of calculations in the current system, but once there is a new data system in place, the Directorate of Immigration will be able provide more accurate statistics.
