Travelling to US on B1 visa when sponsor is not in US

[ignatan]

Hi
I have a situation where my in-laws are planning to visit us at US. They already have 10 year multiple entry B1 visa sponsored by my brother-in-law. But my brother-in-law is no longer in US.
Wondering if my in-laws would face any issues at the Port of Entry. Is any one aware if they need to be taking additional documentation?

No,it does not matter and they do not need to carry any other documentation.

THey can simply say they are visiting you for xxx months. And carry your address and phone no.

For a multiple entry visitor visa, all future entries do not have to based on the original presentation.
