The majority of all my U.S trips over different passports are on the I94 website, as MissM88 has posted above, it's an impressive tool!
@JessicaElle @MissM88 For sure I agree, a friend of a friend isn't ideal, let alone a stranger. I'm sending mine to a very good friend, we went to high school in Australia together so trust her entirely. But all that is asked is that they receive the green card in the mail and keep it safe for you right? For anyone with a stable residence this seems like a small ask (they don't have to actually *do* anything!), but
I guess it's the details people get funny about.. the fact that we are putting their address on a government document as that it involves immigration etc.
