I recently sent my visa application and my passport to the visa agency which I am using via regualar US mail. However, I just read on the website's FAQ that it doesn't reccommend using regular mail and prefers shipping such as FedEx or UPS. I am a little worried about my package because I really don't want to lose my passport. Has anyone done anything similar? Do you think my passport is safe? What should I do if my package is lost? Thanks.
