Hi everyone, so like the title, I sent my application to the P.O box address and I requested a signature so i could track it. (I wasnt able to track it any other way I was told by my local usps) because it was going out of country. I was aware of the courier option but I thought it was only for those within Canada for some reason. So anyways, is my application going to be returned because no one will be at the P.O box to sign for it? I'm super worried now. :/
