I saw this question before, but no answer.
1) Is it possible to transfer from EAD to H1? Can someone please advice me?
---- your employer has to file NEW H1 for you, once approved, go out of US get H1 visa stamp in passport and reenter on H1 status
2) Is priority H1 applicable only to H1 transfers or even new H1 applications?
----- Premium processing is available for NEW H1 also
