I 140 amendment premium processing

[deepapk]

My company has been merged with another company. My PD is current and lawyer has filed EB2 I140 amendment and I485 concurrently.

Lawyer has applied for premium processing for I140 amendment. I have read conflicting threads regarding this issue.

My questions are,

1. Is premium processing allowed for I140 amendment when there is company merger and amendment is based on "succesor in interest".

2. If premium processing is not permitted in this situation, will USCIS send the whole package ( I140 and AOS) back or will they process I140 amendment through regular processing time line? and just deny premium processing request.

Thank you in advance.
