Dear Attorney,
I applied for 485, got an EAD and joined a new company using my EAD. My current status is AOS, as I travelled using AP.
My new employer is applying H1b for me,bcoz my wife who is on H1 need to stop working and come on H4.
My attorney told me - As I am on AOS and have no valid H1b - once my new H1b is approved, I I have to get my H1b visa stamping done in my home country, and reenter USA using H1b, so that my status will change to H1b from AOS.
Q - Is this true? Do I have any other options ?

My attorney also told me that because I am currently on AOS, if I reenter using H1b while 485 was pending, there is a high chance that my 485 gets canceled.
Q - Is this true?

I want to change my status to H1b with out hurting my 485.

Appreciate your suggestions.
thankyou
