All of them denied saying a withdrawl is a final decision and that my current employer is not an affected party. All MTR and Appeal where done to the I140 (in the content we also mention the I485 and AC21).(6) Last decision was received 23 April 2010.

QUESTION

(1) Should I have done all the MTRs/Appeals to my I485 or how the appeal process should've been done? (2) If so Can I still do another MTR/Appeal maybe to BIA?
