老师您好，
又来麻烦您了，我朋友按您说的递交了材料，可是到目前为止没有任何消息，他们很着急？他想请教8老师有没有办法能知道他们的case的进展或者能让移民局加快处理他们的case？我把上次的问题和您的答复复制在下面。
-The process is very slow in these days. It may take about one year to get the visa interview in Guangzhou from the day your friend provided all the required docments and fee to NVC. So, he may just be pateint.
He can contact NVC for the Timeframes. See this link:
He also can check the immigrant visa schedule status at this link:
谢谢啦
