We 'can' send them documents by quoting our UCI and application number.MFAhad said:Can we send documents(like updated LOA) to CIC when our application is in process? I think we can only send them document when CIC asks for it. I am not sure though.
It can be consider in both positive and negative sense.
Positive: It reduces time as now CIC wont send you additional email for updated LOA.
Negative: (first, let me clear, negative is not in sense of REJECTION but in sense of delaying the process) It may delay your process further but don't know how.
