H-1B Revoke/Cancellation processing times
5 attorney answers
The how, when , and where USCIS processes the request for a withdrawal of the H-1B is not germane to your situation since employer B filed the FORM I-129H prior to you ending your employment with employer A. You and employer B should focus on the RFE.
These days the withdrawal acknowledgements are coming in very quickly but you just need to concentrate on responding to the RFE for Company B.
The USCIS will notify you of revocation of your F1 visa with Company A as doors as it receives notice from Company A that you terminated your employment with them. No one can tell you the exact time when you will get the notice.
CIS acts rather quickly, however, what is more important the notification from CIS is that you maintain status.
Attorney Robert Brown's (former INS Director, 1972-99) reply to your question is general in nature, and does not constitute legal advice as all facts are known to him. For specific advice or representation you should retain an attorney experienced in immigration law. Mr. Brown's reply on AVVO does not create an attorney/client relationship not constitute legal advice.
USCIS prides itself into moving very fast on those "withdrawal" notifications once received from the employer. But that should not detract from the fact that both you and your employer, and his immigration lawyer should now put every effort in effectively working on formulating the response to the RFE and getting your new H-1B petition approved. PP or not, employer got 84 days during which to send the RFE response, and you can continue working during that time.
