我的 I-140 好不容易通过了，怪事又让我给碰上了。在 I-140 的 approval notice 上, 在 Section: Skilled Worker or Professional 一栏下面写着：
Consulate: CHENNAI
下面几行小字写着: The above petition has been approved. We have sent it to the Department of State National Visa Center (NVC), 32 Rochester Ave., Portsmouth, NH 03801. NVC processed all approved immigrant visa petitions that need consular action. It also determines which consular post is the apporpirate consulate to complete visa processing. THe NVC will then forward the approved petiton to that consulate.
This completes all USCIS action on this petition. If you have any questions about visa issuance, please contact the NVC directly. The telephone number to NVC is (603)334-0700. Please allow 90 days before contacting the National Visa Center regarding your petition.
这是啥意思啊？有人知道吗？我该怎么办？(本人现在 U.S.) 多谢多谢!
