Cancellation of B-1 Visa

Need your help in understanding the cause and impact of my B1 visa cancellation.

I have more than 4 years of IT experience, and I have traveled to US four times (on B-1)few years back from my employer.
My first and second and third visit was for 3 months, and my last visit was for 6 months (I-94 was provided for 6 months). I stayed around 15 months in US with in two year.
Later i requested my employer to process H-1B. When i went to consulate for H-1B stamping, Visa Office particularly asking about my previous visits did not consider my H-1B. After i conformed that i visited four times and stayed whole visa duration every time, he cancelled my B1 visa. For H-1B he requested to submit additional documents for verification.

Would like to know how this cancellation of my B1 will impact my H-1B, If don't get H-1B how it will impact if I would apply any other visa.

How can i get to know B1 cancellation with prejudice and without prejudice.

Many thanks in advance.

It appears that the consular official had some concern about the types of business activities you participated in while on B-1 status. It is quite likely that your employer had you engaged in improper business activities if you were in the US for 15 months in a two year period.; if that is the case, it is your employer that is preventing you from obtaining H-1B stamping. You may have better luck with a different employer without the history of your current one. However, any improper work activities on your part are a potential issue; a guest worker is required to understand what he is legally permitted to do on any specific visa.

No one can predict the chances of any visa stamping. Obtaining another B-1/B-2 will be more difficult than your first stamping based on your history, but you are not likely banned.
