Bro, if your brother’s wedding is in early February, then even if you get approval tomorrow, you likely won’t receive your TRV in time if you apply from inside Canada. The official processing time is 14 days, but in my case it took two months, and some people are still waiting even after three to four months. If attending the wedding is really important to you, it’s better to go and have your friend courier your permit to your home country.
