Why is it so difficult to make friends with americans?

I live in Katy, Texas since 2007. I arrived to the USA on August 26, 2007 from eastern european country. And since that time I am trying to find friends with Americans. But local Americans do not want to communicate, they ignore all my attempts to talk with them. And I can not understand why. Please explain to me how I can make friends with Americans and what are the right and possible ways to do that. Thank you all who will answer my questions in advance. God Bless you.
