What arrangements should I do to get the visa to travel to USA?

I am a bodybuilder from Egypt, and I got an invitation from Bodybuilding federation in the USA, I went to the American embassy in Egypt to get the visa to travel and participate in a championship, they refused me. I want a real way to travel, what is it ??? They people in the embassy tink that Egyptians want to travel to USA to work there, but I am not.

Thank you!

You only need a visa if you plan to stay and work here. If you are only visiting, a passport is sufficient.

If the invitiation to which you are referring is an invitation to work then that organization should be doing the paperwork for you (they have to, as the sponsoring employer).

sounds like you went the right route. contact the embassy again. some countries are given quotas each year and it can take up to 3 yrs or more. ask advice from the bodybuilding federation, too.

How many other international events have you attended? Are you ranked in the world rankings? It's sounds like this is your first trip abroad. It's going to be difficult to obtain a visa until you have some experience.
