What happens in this situation:
I am a AOS parolee per I-94. I keep working on existing H1 for sponsoring employer. If I start with new employer using EAD and new employer files H1 what will happen?
a. H1 petition gets denied.
b. H1 petition gets approved, but I do not get new I-94 with H1 status.
c. H1 petition gets approved, I get new I-94 with H1 status.
In case b. am I authorized to work for new employer using EAD only (until I re-enter with new visa stamp) or I can file W-9 to change work authorization document to approved H1?
