Fax a letter to 613-995-1304 (Citizenship Court-Ottawa) and ask for a reschedule of the test since you couldn't make the first one. You need to identify your file number, application ID and name in your letter. You also need to attach the original letter you received from CIC. If you don't do that, they will never reschedule another test for you automatically. TRUST ME! Don't try to call the call centre if you are in China. It is just a waste of your time and money. The call centre only provides general information, and each rep there may give you different answer. In addition, the call centre cannot tell anything about your current status, because your file has already been transfered to the local office. I got caught two months ago. I was scheduled to take the test on April 27. For some reasons I just couldn't go on that particular day. So I called the call centre. They told me that I can wait and the local office will reschedule another one for me if I don't show up. After two week anxious waiting, I went to the local office. I was told that I should have came to explain that I couldn't take the exam at very beginning, or at least send them a letter. Since there is no room for May, they have to reschedule it in June. Then they found out my security clearence would expire by the end of May, and they had to apply for my security clearence again!!! I am still waiting.
