Common mistakes that IRCC may send the file back...
1. Make sure you sign and date the require documents.
2. Send original IELTS-General certificate.(i thing only in AIPP they need original certificate,in other programs they just need a copy)
3. Send ECA along with clear copies of your education credentials.
4. Don’t forget to attach 2 photos,1 blank and 1 stamped,dated,and signed by studio on the back along with your name and DOB,
5. One of my known paid the PR Fees 1040 CAD and after two months he called the bank that he did not authorised this transaction the bank returned the money and money was taken back from canada immigration too. So his PR file was declined because the fees he paid for processing was taken back by the bank. He tried to save his 1040 CAD and end up getting rejection for his PR file(Don’t try this credit card fraud it can work with buying a phone online but don’t try to be clever here)
6. Pay your PR fees on your own,usually immigration reps take money from you but don’t pay it to cic which ends up getting your file returned to you.
7. Don’t wait for PCC to send it upfront with your file,you can submit it later when IRCC requests it. It will save one month of your processing.
