暑期交流旧签+新I20入境问题

本人19年暑假交流时候获得的五年F签，目前想年底柬埔寨洗白入境ATL，发了邮件问CBP回复是
Thank you for contacting U.S. Customs and Border Protection's (CBP) Information Center.

You can request entry to the United States with a valid visa, a valid passport, a new I-20, and a new SEVIS ID.

Students returning to the United States to resume their studies after an authorized temporary absence do not need to renew their visa if it is still valid. Although the date on a visa may indicate validity, occasionally there is a mistaken cancellation. It is highly advised that such a student contact the Designated School Official (DSO) at the school in the United States to determine if the visa remains valid. CBP recommends checking visa validity before attempting to travel to the United States.

The CBP Information Center is not able to check the validity of a visa issued by an American embassy or consulate. You are encouraged to contact the United States embassy or consulate where your visa was issued to check on the validity of that visa. Contact information is available on the official U.S. State Department Web site www.USEmbassy.gov.

Thank you again for contacting our office.

其实只有第一句话有用，于是发邮件问了国内大使馆，给了护照号和签证号，收到回复是：
Thank you for writing to the US Visa Services Desk.
We understand you would like to know if your student visa is still valid.
Please find below information: Validity of Student Visas After a Break in Studies
Students who are away from classes for more than five months must apply for and receive a new F-1 or M-1 student visa to return to school following travel abroad, as explained below.
后面一串就是格式化的回答。
所以他还是没告诉我签证是否valid，同时也已经翻过地里面之前很长的那个旧签讨论帖子。

目前有几个问题：
1. 怎么单独联系到某个机场的cbp，比如ATL CBP
2. 交流（非美本）旧签入境是否合法
3. 怎么查签证是否valid，查询了DS160那个号码，显示visa issued，也查不到是否有效
4. 按照CBP说的，是否有人联系过DSO问visa valid问题，回复是啥

已经有至少几百个旧签入境的例子了，很多学校比如哥大康奈尔的iso都是说可以的，海关也是可以的，就像你的旅游签十年美签并不会因为你去过一次了就作废呀，F签本身也是有效期内多次往返的，不管学校名字是不是一样，只要你给你的新sevis交费了就是合理合法正常入境的，F1仅仅是证明你有进门的资格，i20才是证明你有合法停留的资格，区分开这两个你就不会有顾虑了

谢谢你啦，哈哈也是有点焦虑才发的，再加上国内大使馆无论中文发还是英文发都说要重新弄，才感觉有点担心

sevis id 如果沒有變是transfer過去的話完全沒問題 如果新的之前看網上資料似乎說是需要重新申請visa 供參考

蹲回答哦 同打算用这种方式冲

没有问题的 只要你的sevis i20之类的都是更新的新的即可
