I was reading through the CEC manual (Jan 2013)
http://www.cic.gc.ca/english/resources/manuals/op/op25A-eng.pdf
the officer is unable to make a decision, due to lack of information or documentation, or there are serious doubts as to the legitimacy of the documents submitted
- request, in writing, specific information or documentation to clarify; or
- refuse the application; or
- consider a personal interview
We have always seen the Officer going with the 2nd option of refusing the application directly. Do we have any cases where additional info has been called or interview ?
