Visitor Visa - B2

i am G N REDDY from hyderabad

I have been to US consulate Chennai for H1 B Visa in May 2001, I have been denied visa
U/section 212(a)(6)(c)(i) misrepresentation of material facts- Fake work experience letter.
Actually what happened at the time of interview , consulate officer asked me to wait & called my employer at hyderabad ,
At that time my boss was not there in office , someone picked up the phone who doesn’t know my exact salary. Hence He has not given my salary particulars correctly,
 Consulate official misunderstood me & imposed sections mentioned above.
Recently on 18-1-2013, I attended the U S consulate for’ B2 visitor visa’
To visit my son who is in US on H1 B visa status, I have been denied visa under section 214(b)
Stating that I have committed fraud in 2001,
Now I want to know that is there any procedure to exonerate me from the above fraud sections ?
Whether I can get B2 visiting Visa in the future, now my age is 59 years.
Whether it is a life time ban for me to visit USA ?

please give advise to my mail id. [email protected]
