新签证 换了i20 需要重签吗

不需要，你如果不离开美国你的F-1签证是永远有效的，但要相应跟随一个有效的I-20，现在留学签证是五年，是指的五年内你只要持有效的I-20你就可以自由往返中国，过了五年即使你有有效的I-20在美国仍然合法，但回国就必须再签证。

不需要重新签证，这是官方的说法： it is not necessary to visit the u.s. consulate/embassy for a new f-1 visa unless the current f-1/j-1 student visa in the passport has expired or will expire before date of re-entry to the u.s. re-entry to the u.s. will require students to show the following documents at the port of entry: passport (valid at least 6 months into the future) valid f-1/j-1 student visa in passport a new school transfer pending i-20/ds-2019
