小白兔，
I took an offer from company A, working there for two months and then joined company B.
Company A applied H1B transfer for me before I started there. Of course, the application was not approved even after I left there.
Company B started a premium H1B transfer for me and got it approved in 10 days. So, I got H1B approved for company B before working for company B.
So far I have been working for company B for about 1 month.
Now, I was noticed the H1B for company A was approved.
How could this happen? When company B transfer my h1B, I put company A in my resume.
My questions are:
Am I still legal working for company B?
What should I do in this situation?
Company A is a tiny start-up. I guess they forgot to withdraw or did not do to avoid more costs.
