我收到下面的电子邮件。问题是1. 我最近没有被notified, 不知道他们指的是书信还是电子邮件
2. 信里提到他们会帮助预约面试，我是接着等电子邮件吗？最长时间是等多久呢？
Greetings from NVC:
You were recently notified that we are now ready for you to begin filing your application with the National Visa Center. Our role is to collect fees, administratively prepare you for your visa appointment, and schedule your interview. Some people can find these steps to be difficult, so we would like to provide a few helpful reminders as you prepare your application.
