From an older post http://www.mitbbs.com/article_t/Immigration/32157455.html: Q: Can Concurrent Filing Be Used If More Than One I-140 Is Filed on Behalf of the Same Beneficiary? A: Yes, with a few caveats. Generally, if an I-140 is filed seeking to classify a foreign national as an alien of extraordinary ability and a separate I-140 is filed requesting a national interest waiver for the same foreign national, he or she may submit , at the same time or subsequently, an I-485 with one of the I-140 petitions . USCIS has said that only one I-485 per applicant may be filed at a time. If more than one I-485 is pending, USCIS may request that one of the I-485s be withdrawn. The first caveat is if the I-485 accompanies the extraordinary ability I-140 , but the national interest waiver I-140 is approved first, USCIS will not transfer the I-485 to the approved I-140 until the extraordinary ability I- 140 has been adjudicated. If the extraordinary ability I-140 is approved, the I-485 will, in all likelihood, also be approved. If the extraordinary ability I-140 is denied, and the priority date for the national interest waiver I-140 is current, USCIS will usually, but not always, match the pending I-485 to the approved petition. If the extraordinary ability I-140 is denied, and the priority date for the national interest waiver I-140 is not current, USCIS will not transfer the I -485 to the national interest I-140. USCIS can only transfer the I-485 if a visa number is available for that I-140 petition. Therefore, when the extraordinary ability I-140 is denied, and the national interest I-140 is approved but the priority date is not current, the I-485 will be denied. The second is if the I-485 accompanies the national interest I-140, and the extraordinary ability I-140 is approved first, again, USCIS will not transfer the I-485 until the national interest I-140 is adjudicated. If the national interest I-140 retrogresses, meaning the priority date is no longer current, USCIS can still transfer the I-485 to the extraordinary ability I- 140 as long as the extraordinary ability I-140 remains current. Finally, if the I-485 accompanies one or the other of the I-140s, and that I -140 is denied, and the other I-140 remains pending, USCIS may match the I- 485 to the pending I-140 as long as the pending I-140 remains current. If this is missed by USCIS, and the I-485 is denied, it may be necessary to file a motion to reopen.
USCIS has said that only one I-485 per applicant may be filed at a time. So now you can request them to consider you I-485 based on the approved EB2, since your EB1-140 is still pending. I think they will still continue to consider your EB1 case if you did not withdraw.
