Dear friends I am in a very difficult situation, Please help me in my situation below:

I am working part time hourly in company A, they are paying me 12% less per hour rate than the rate in LCA for nine months.

Due to approaching lay off, I have to move on so I am transferring my H1b to company B, will there be any problem to transfer to company B due to this less pay issue in my pay stub?

If there will be problem, what would be the best solution for the problem?

Can I go to talk to my employer to pay me that 12% for those hours I worked in nine months? And if my employer pays me, will my problem be solved? If so how?

I appreciate your time and help. Thank you so much.
