鉴于有些人不知道，EVUS 代表的是签证更新电子系统，是由我们美国国土安全部的同事开发的新系统。2016 年 11 月开始，所有持有 B1、B2 和 B1/B2 签证的中国公民在前往美国之前还需要在 EVUS 登记。自从我们开始给中国公民签发 10 年签证，我们看到了申请的大量增加，我预计我们将持续看到数百万中国公民前往美国。我们非常高兴 10 年签证可以在这里实施！
在 EVUS 上更新信息将有助于为签证持有者进入美国提供方便。任何进入美国的人如果拥有为期 10 年的签证，都将既需要签证也需要有效的 EVUS 登记。请注意，前往美国的旅客只需要每两年在 EVUS 登记一次。在 EVUS 登记的程序设计得尽可能的简便易用。它是一个在线系统。
没有必要去银行。没有必要找旅行社代理。没有必要来使馆。你一获得你的签证就可以在 EVUS 登记。虽然登记过程应该非常快，我们建议你至少在出行前一周进行登记。
你可以在任何可以连接互联网的地方在 EVUS 登记。你将能够使用你的电脑、笔记本电脑或智能手机登记。这件事很容易，可以自己做，也可以让朋友或家人或其他第三方代表你来做。
小王是一名二十岁的中国学生，在美国留学。她有 5 年的 F-1 签证。她今年夏天回中国看望她的家人，然后返回大学。前往美国之前，她并不需要在 EVUS 登记，因为 EVUS 只面向 10 年 B 签证持有人小王的母亲打算与她一起前往美国，去看看女儿学习的地方。小王的母亲 7 月从美国大使馆获得了 10 年 B1/B2 签证，并与小王一起在 8 月前往美国。虽然她拥有 10 年签证，她并不需要在这个时候在 EVUS 登记。该系统要到 11 月才会启用。小王的母亲很享受她在美国的短期旅行，并希望在 2017 年 1 月春节期间带她丈夫，也就是小王的父亲，到美国旅游。小王的母亲可使用她的有效签证，在于 11 月启用的 EVUS 系统上登记，而且她必须在旅行前登记。她不需要另外申请签证。
小王的父亲 12 月从美国大使馆获得 10 年 B1/B2 签证，他可以一获得签证就在 EVUS 登记。他必须在赴美前在 EVUS 登记。小王是一个好学生，即将于 2019 年春天毕业。她想让她的母亲、父亲和祖父母参加毕业典礼。她的父亲已经拥有有效的 10 年签证和有效的 EVUS 登记。所有他要做的就是买张机票去美国，因为旅客只需每两年在 EVUS 上更新其信息（除非他们获得了新护照）。
小王的母亲也拥有有效签证，并在不到两年前进行了 EVUS 登记。不过，她换了一本新护照，因此她需要在 EVUS 上再次登记。小王的祖父母以前从来没有旅行过，所以他们都需要获得 B2 签证，并在赴美前在 EVUS 登记。EVUS 登记两年有效。但是，如果小王的祖父母很长一段时间不再来美国，他们要到临近下次旅行之前才需要再次在 EVUS 登记。比方说，他们要在 2024 年去度假，他们只需在旅行之前再次登记。
我希望这些虚构的小王一家的例子能帮你解答有关 EVUS 运作的问题。如需了解更多信息，请访问：EVUS 官网。最新的信息将公布于此。
Thank you for your EVUS questions. For those of you not aware, EVUS stands for the Electronic Visa Update System, a new system developed by our colleagues at the Department of Homeland Security. Beginning in November 2016, all Chinese citizens who hold B1, B2 or B1/B2 visas will also need to enroll in EVUS before travelling to the United States. Since we began issuing ten year visas to Chinese citizens, we have seen a large increase in applications, and I expect we will continue to see millions of Chinese citizens travel to the United States. We are very happy that the ten-year visa is here to stay!
Providing updated information in EVUS will help facilitate entry into the United States for visa holders. Anyone entering the United States will need both a visa and a valid EVUS enrollment if they have a ten-year visa. Please note that travelers to the U.S. will only need to enroll in EVUS every two years.
The process to enroll in EVUS is designed to be as easy to use as possible. It is an on-line system. There is no need to go to a bank. There is no need to go to a travel agent. There is no need to come to the Embassy. You may enroll in EVUS as soon as you have your visa. While the enrollment process should be very fast, we recommend enrolling at least one week before your travel.
You may enroll in EVUS anywhere you have internet access. You will be able to enroll using your computer, your laptop, or your smartphone. It is easy enough to do yourself, but a friend or family member or other third part could also do it on your behalf.
Let’s walk through a few examples to see how the process will work.
Xiao Wang is a twenty-year old Chinese student studying in the United States. She has a 5 year F-1 visa. She comes back to China this summer to visit her family and then return to university. Before travelling to the United States, she does not need to enroll in EVUS because EVUS is only for holders of ten year B visas.Xiao Wang’s mother plans to travel with her to the United States in to see where her daughter studies. Xiao Wang’s mother receives a ten year B1/B2 visa from the U.S. Embassy in July and travels with Xiao Wang to the United States in August. Even though she has a ten-year visa, she does not need to enroll in EVUS at this time. This system will not begin until November.Xiao Wang’s mother enjoyed her short trip to the United States and wants to bring her husband, Xiao Wang’s father, to see America in January 2017 during Spring Festival. Using her valid visa, her mother can enroll in EVUS starting in November and is required to enroll before travelling. She does not need another visa. Xiao Wang’s father receives a 10-year B1/B2 visa from the U.S. Embassy in December and can enroll in EVUS as soon as he receives his visa. He is required to enroll in EVUS before travelling to America.Xiao Wang is a great student and is graduating in the Spring of 2019. She wants her mother, father, and grandparents to attend the graduation ceremony. Her father has already has a valid 10-year visa and valid EVUS enrollment. All he has to do is buy a plane ticket and go to America because travelers only need to update their information in EVUS every two years (unless they get a new passport). Xiao Wang’s mother also has a valid visa and enrolled in EVUS less than two years ago. However, she got a new passport, so she needs to enroll in EVUS again. Xiao Wang’s grandparents have never travelled before so they need both a B2 visa and to be enrolledl in EVUS before travelling to America.EVUS enrollments last for two years. But, if Xiao Wang’s grandparents do not travel back to the United States for a long time, they will not need to enroll in EVUS again until just before they travel. Let’s say they travel on vacation in 2024. They will need to enroll again just before that trip.
I hope these examples of the hypothetical Wang family help answer your questions about how EVUS will work. For more information, please visit EVUS Official Website . The latest information will be posted there.
