Thanks! I'm in the USA now, and I'm wondering if it is possible for me to use USPS. I read some application procedures from people who applied for Canada visas previously, many of them use USPS and they didn't mention shipping label.
I am an international student too! I have read some instructions from people who applied for Canada visas previously, they said there's no need to use a shipping label. I am so confused if the shipping label is mandatory?
