十分感謝8老師，麻煩再請教一下，
1. 如果EB1-140被拒，是不是就無法relink 485到EB2的140了？
-I think so because when the EB1 I-140 is denied, the I-485 will also be denied.
2. 如果在EB1-140結果下來之前relink 485到EB2的140，但是之後EB1-140批準，是否可以再relink回來，還是相當於就放棄EB1的485申請了？
-The relink/interfiling means one I-485 can be considered based on any one of the two or more approved I-140s. So, if you do the relink successfully, USCIS will automatically consider your pending I-485 based on either approved EB1 I-140 or approved EB2 I-140 and you do not need to do anything. Also, after relink, even if your Eb1 I-140 is denied, your I-485 is still valid and will be approved based on your EB2 I-140. So, I-485 = two I-485s.
