Thanks mate..+1 for you.
Century said:You can consider checking the remark column of Mr vivesehg in the spreadsheet (row 18). He got PER. I added those remark from his thread. The following is the remark
"Used 10th class marksheet for me and my spouse. No affidavit or cover letter. I put sticky note on 10th marksheets stating 'birth date proof for applicant/spouse'. sent PCC from FBI which was 7 months old."
So, CIC accept 10th class marksheet without any affidavit or forwarding letter. But I suggest to add a forwarding letter mentioning all details.
