Getting a waiver for a material misrepresentation is very, very, difficult.
You need to meet in-person with an attorney (this could be by Skype).

Also, keep in mind that this is an INTERNET BLOG. You should not rely on anything you read here to make decisions which impact on your life. Meet with an attorney, via Skype, or in person, to obtain competent personal and professional guidance.
Once you misrepresent yourself in any way to ICE/DHS, you can't get a visa without a waiver excusing that behavior. It's going to be extremely difficult to get a waiver that will allow you to secure another B2 Visitor Visa. I would strongly recommend you schedule a consultation with an attorney experienced in this area. And as my colleague suggests, many of these can take place over SKYPE.
