回复：请教坛中各位大师

为父母申请移民，移民局已寄来I-130的approved notice，并说转去nvc，请问nvc的处理步骤是什么？

-NVC will contact you and send you the instructions. Then, you just need to follow the NVC instructions to do what they ask.

大概需要多长时间？

-NVC will send you the instructions by several times. The first time may occur in one to two months.

本打算回国一段时间，但是在没有完全处理完美国段的移民手续前真不敢离开。谢谢！
