Hi everyone,

I work for company A on H1B and have an offer to from company B. I have not disclosed this to company A as I want company B's h1b transfer to be approved first.
Company B is working on my h1b transfer petition and has asked for letter of employment confirmation which has to be signed by company A stating the positions worked in and what job duties were performed in that role.
Now, I cannot ask for this document from my current employer company A as they are not aware of my intend to move. If later the transfer petition by company B gets rejected for some reason and I have to continue working for company A, then it will be an awkward situation.
Company B says the petition might be rejected without this letter of employment confirmation. Please can someone advise on what can be done in this situation? Is there an alternative way by which the document can be arranged?
