Man415 said:I would strongly suggest include a cover letter on the application form stating again the reason for application and the CIC request letter.Also indicate that in case they won't allow a proxy to claim the letter to send it to the requesting office.the fee that you are paying includes the stamp fee sending it to the requesting office.Again as I haven't use a proxy I am not sure if they would really approve a proxy.If they would send it via snail mail, it's registered with tracking number, but ordinary and not express so for me it took 18 days for NS CIO to receive it.processing took 21 days plus the 18 days sent via mail.I would suggest do it NOW as the 60 days that CIC require might not be enough for SG COC.Fortunately for me my SG COC arrived in NS the very last day of the deadline given to me.
Thank you so much Man415 for answering all my doubts.
