International Survey Sites!!!??!?

I had joined couples of international survey sites, some of them offer you cash and some offer you a chance to win money. I did not get paid from any of them, but I was told that i won a prize of $50, and i m waiting for the payment. I notice that if you are in the US , you will have alot of invitations, if not, you may not get a lot of chances to participate in the surveys even thohugh they are not scams.

When I first started using the internet at home about 13 years ago I joined an opinion poll in the US that sent me emails to participate in consumer surveys. They didn't pay per survey but had a weekly or monthly drawing and the winners got paid. I was just doing it for fun but shortly after I started they started sending me $10 checks in the mail. It usually cost me a bit to transfer the money into Icelandic money so it wasn't really much but it was fun to see that they did actually pay and even to someone that far away. After I changed my email address I forgot to inform them so I don't know if that site is still running. I think name of it was Opinionsite but I can't really remember. Most of the survey sites I have seen lately are only for people who live in the area. I have signed up for a few of the ones that say they want people from all over the world but they never sent me any surveys.
