Do not be too much excited about conversion
I filed my conversion case two months ago, they have not withdrawn my BEC case yet since BEC had not sent 45 days letter so far and BEC could not locate my old case to verify with new case, so my conversion case dormant at PERM as well as old case @ BEC. no use of PERM conversion if you have not received 45 days letter, it may be helpful for who have received 45days letter and waiting for BEC decision.
No 45 days letter yet
PERM Conversion filled on 02/07/06
