Business Visa - B1

    Hi i have applied for f1 student visa in 2011 april and may twice and was rejected and gave me a 214 b slip and advised me to do my research better and come back. I have lost hopes and never bother to apply again, however fortunately after three years my company is applying b1 for me for 3 mnths. am ok to go for the interview but the only problem was when i applied for f1 i stated i was wrking for some software company which i never worked and at that time i was working for the same company thats sending me now so am scared and nervous. i know it was due to bcoz of consultancy ppl advise i took fake experience but they never doubted that but now that i am going to apply for b1 and i will mention that i am working for this company. can some one please help me and explain how to answer and go abt it. will they cross check my previous rejections and also go and check at that time wat was company i was working for? please help and reply fast as i have an interview this week and scared to death abt this. wat can i do to improve my chances or will they caught me? please reply me as much as infrmatio possible apart from me praying thanks
