虽然每个赴美签证都有个有效期,但是,对于F-1和J-1签证的留学生来说,在第一次赴美的时候,却有一个规定,那就是即使你提前去签证,签证有效期可能在开学日期的120天前,你也不可以提前入关。因为对于F-1和J-1第一次赴美的学生,你最多提前30天赴美。
如果你想提前赴美,那么,你就不能够用学生签证的身份。你可以以别的理由去签证,在美国停留的有效期内,申请转换身份。
当然,你不可以先去签一个F-1,然后又去签一个旅游。第一美国留学建议第一次赴美的留学生如下操作:
如果你是已经在美就读的学生,只要你有有效签证,就不会再受开学30天以内才可入关的限制。

当然,你不可以先去签一个F-1,然后又去签一个旅游。第一美国留学建议第一次赴美的留学生如下操作:
- 当你收到I-20以后,尽量提前去签证。美国国务院规定,美国使领馆只可以根据你的I-20报到日期提前120天给你签证。
- 尽量提前预订机票。每年到夏季的时候,中美之间的机票就会至少涨上天。
- 赴美的日期根据机票价格和你在美国落脚的安排综合考量
如果你是已经在美就读的学生,只要你有有效签证,就不会再受开学30天以内才可入关的限制。

When Do I Need to Apply for My Student Visa?
- Students are encouraged to apply for their visa early to provide ample time for visa processing. Students may apply for their visa as soon as they are prepared to do so.
- Students should note that Embassies and Consulates are able to issue your student visa 120 days or less, in advance of the course of study registration date. If you apply for your visa more than 120 days prior to your start date or registration date as provided on the Form I-20, the Embassy or Consulate will hold your application until it is able to issue the visa. Consular officials will use that extra time for application processing.
- Students are advised of the Department of Homeland Security regulation which requires that all initial or beginning students enter the U.S. 30 days or less in advance of the course of study start/report date as shown on the Form I-20. Please consider this date carefully when making travel plans to the U.S.
- A beginning student who wants an earlier entry into the U.S. (more than 30 days prior to the course start date), must qualify for, and obtain a visitor visa. A prospective student notation will be shown on his/her visitor visa and the traveler will need to make the intent to study clear to the U.S. immigration inspector at port of entry. Before beginning any studies, he or she must obtain approval for a change to Exchange Visitor status, filing Form I-539, Application for Change of Nonimmigrant Status and pay the fee. Also you must submit the required Form I-20 to the Department of Homeland Security office where the application is made. Please be aware that one cannot begin studies until the change of classification is approved.
- Continuing students may apply for a new visa at any time, as long as they have been maintaining student status and their SEVIS records are current. Continuing students may also enter the U.S. at any time before their classes start.
