Dear Ahmad06, if you applied before 26 June and already got 1 Aor these changes don't refer to you but if you are starting appl process after 26 June you must to pass General IELTS, it's new regulations of CIC. It says:
* Include the results of your test with your immigration application.
Note: If you do not include your test results with your application, it will not be processed and will be returned to you.
Do not request that your language test result be sent directly to the Centralized Intake Office . Submit your original test result with your complete application.
Note: IELTS has two options for the reading and writing tests: “General Training” and “Academic.” You must take the “General Training” option.
