Canadian visa denied. Can I sign it again?

You can sign it again, but Canada does not accept complaints. When to sign again after rejection has nothing to do with time. The key is whether your binding force is stronger than last time. If the binding force is more than last time, you can sign it again at any time. If you don't change anything, that is, the binding force remains the same as last time, even if you sign in 10, the result will still be rejected, so when you can sign again after being rejected has nothing to do with the time, mainly depending on whether your binding force has increased compared with last time. As long as you add it, you can sign it again right away. If you need help at that time, it is recommended to consult Gao Shen. Com, a state-owned enterprise specializing in visa refusal and re-signing, has helped many applicants who were refused visas in Canada get through. Good luck with your next visa!
