H1B transfer denied - from company A to B

[jananinm]

I was in H1B transfer process from Company A to B.
1, I have first I-797A approved till 2020 Dec from "Company A"
2, Later in 2018,due to project amendment I-797A changed to June 30 2019 from "Company A"

I have changed the H1B from company A to company B and joined company B with receipt notice in Jan-2019.

3, Now H1B transfer denied due some job code with company B,

However company B attorney raised Qtn with USICS <-- with new petition on premium process which is in progress now

Please let me know

4,What is implication ?
5,How much time time it may take to get answer from USICS ?
6,Will this be concerned as out of status ?
7,Should may arise situation to leave country ?

Thanks in advance.
