I am US citizen and planning to sponsor green card for my sibling. My sibling has already visited US in B-1/B-2 visa few times and holds that visa for another few years.
I know that this kind of application takes 10+ years to approve. From this context in mind, I have few questions -
1) Can my sibling enter United States on the same B-1/B-2 visa after I apply immigration application?
2) Can my sibling apply for renewal or new B-1/B-2/H-1 visa while application is being processed?
See clip from Attorney Rajiv S. Khanna's conference call video that addresses this question.
