使用AP回美国以后H-1B就失效了而必须使用EAD, 这是真的吗?
- not true

When you come back to US and work for the same employer without using EAD, you are still in H-1 status even if you have used AP. In such case, you're still eligible to extend your H-1 or transfer H-1 to another employer without breech to your H-1 status. Remember, no EAD is ever used.
