I need to convert my Type of visa B1/B2 to H1 or any other type to work in USA?can I know how can make it ?

Your question is too general to be answered without knowing your qualifications and/or any connections that you may have with companies and individuals in the US. However, let me shortly describe for you the H-1B process. Most H-1B petitions begin with the employer registration process in March to winnow the number of selected companies/individuals that can file petitions. These are the petitions that are capped in number. Most petitions from this group are filed from April-June and the earliest working day for approved petitions is October 1. Non-capped petitions filed by higher educational institutions among others can be filed at any time during the year.
