Could just be a coincidence you have never got anything back from the u.s. or its possible since you live in isreal someone at your post office doesn't like America and is throwing them out because a lot of countries don't like America or maybe someone is stealing them thinking if its from America it might be worth something. Its really a impossible question to answer.

Hello,
I have a weird problem and I found this place the best to find an answer.
I live in Israel and I sent many autograph requests to celebrities in the world. I got a response from all but not from those in the U.S.
I sent an autograph request to government members, actors (from different Management Companies) and have never got any response from any celebrity in the US. All of the requests were sent at least 1 year ago..
I even sent them a self addressed envelope with international stamp. I asked them to sign and dedicate it to me, so I don't see any reason why I don't get a response from U.S celebrities.
Any Ideas?
Thank you!
