Tips for Preparing Application
- Do not leave any time gaps in work history, education etc
- Attach requested documents in application
- If traveled out of Canada, provide documentation for that if possible, if stamp is not in English translate it
- Keep school records copy of child/ren
For test
- Read book thoroughly - read notes under pictures displayed on side
- Practice test online (search forum for more links) - My recommendation (citizenshipcount.ca) it is sufficient for preparing do not buy/spend money for preparing
At test -- All CIC officers are polite and helpful. Test is not stressful -- if you are prepared well. Interview is just normal conversation for testing your English/ French skills.
Again thanks to all who helped me during my process.
