Can a B1/B2 Business & Tourism visa be extended for another six months? How to do that?

To extend your stay in the US, you would have to apply on form I-539 Application To Extend Or Change Status and your family members would have to fill out separate I-539A dependent forms. You would have to state your reasons for staying, give assurances that you will be going back at the end of the six months, and show ability to support yourself and your family for the time period without having to resort to employment. As the principal, you would have to pay $370 and each of your dependents $85 to the US Department of Homeland Security.
