Raj,Because that is how the workflow is designed.
When your test is validated, you'll see the "Citizenship Test" status on the New Citizenship status Dashboard set to "Completed".
After this, you might get an interview invitation. If you don't get an interview invitation, then the next update on your application will be "Decision Made" on ECAS and "Prohibitions", "Language" and "Physical Presence" will be set to "Completed" on the new dashboard, concurrently.
I gave my test on June 11 and it got updated on June 14 to 'Completed'.
What is the expected timeline between this and getting the next step (Decision made)?
