請問8老師，
我給我妹妹申請綠卡，最近收到移民局通知：
On nnnn 2020, we sent your case, Receipt Number mmmmm to the Department of State for visa processing. You can find general information on Consular Processing by visiting our website at www.uscis.gov .
這是啥意思啊？移民局已經批準了？要走下一步申請移民綠卡啦？我該幹什麽啊？可以等綠卡名額了？我再研究一下，也請8老師指引方向，謝謝！
-That means USCIS forwarded the approved I-130 to National Visa Center (NVC) for processing for your stsier's application for the immigrant visa. You just need to wait for NVC to contact you and send you the instructions.
