send a letter to CIS to ask for interfile your two 140. Submit copies of your approved documents, 485 receipts and coverletter.
The USCIS confirmed that it will continue to permit interfiling of I-485s when a person obtains two I-140 petition approvals. Interfiling is essentially the transfer of a pending I-485 application to adjust status from one I-140 petition to another filed for the same beneficiary. Examples would be when there is a successor employer, or an I-140 petition filed by a new employer or with the same employer based on a new and different job offer. This eliminates the need to re-file the I-485 in many situations, if there is a second I-140 petition to support the pending I-485.
