 It is best for you to find an employer who is willing to sponsor you on your Working Visa since you enter on a B1/B2. Once you find an employer he/she can process a H1 Visa or working Vsa for you. But first of all you need to check whether you arrived in the USA with a tourist visa, or on the visa waiver program. Check your I-94 card in your passport. If it is green, you have a visa waiver. If it is white, you have an actual tourist visa.
