請看本文最下方 Additional Information

"Individuals who are already in the U.S. and remain in legal status are encouraged to apply at non-border U.S. embassies and consulates in conjunction with foreign travel for business or pleasure. Those who plan to visit Canada, Mexico or, in the cases of students and exchange visitors, adjacent islands, may re-enter the U.S. within thirty days on expired visas as long as they possess a valid I-94 form unless they are excluded from automatic revalidation, as noted below. "

我覺得都能回來 唯一造成回不來的原因 如果摳字眼兒的話 在于那個 expired visa
你在面簽的時候 即使出現被check 或者當天拿不到的情況 一定和簽證官說兩句好話
不要讓他把你那個expired visa canel 如果上面有個大cancel章 就會有一點危險
情況.

邊防不讓你進的原因是 你雖然有有效I-94 I-797或者I20 但是你的那個expired
visa已經不存在了.

當然 還是要看運氣 我想因為被check回不來的人畢竟少數 我個人也知道一個 論壇上
有過來人都說了 這個邊防官說你不能過 再排隊 試試另外一個 不行了 找個旅館蹲
一晚上 再試 大家仔細想想 那些邊防官對于美國移民法律不一定比咱們好

入關的時候 I-797 / i20 放在I-94那一頁 再把剛才打印出來的條款 highlight 帶
著 或許會有一點幫助.

我明天就要去了 而且我的I-797傳真過去還沒有信息.

Re-Entry into the U.S. - Important Information

The U.S. Government has undertaken a variety of efforts since September 11
to enhance border security. Anyone who has applied for and been refused visa
issuance at a border post is prohibited from re-admission or re-entry to the United States in the same visa category, even though they are in possession of a valid I-94 form. Aliens who are citizens of countries on the State Department's list of State Sponsors of Terrorism are prohibited from re-entering the U.S. using solely an I-94 form if their visa has expired.

Citizens from State Sponsors of Terrorism countries must obtain a new visa (and thus go through a new set of interviews, computer checks, etc.) rather than re-enter the U.S. using solely their I-94 form.

再看最后一段里面的一句話 Anyone who has applied for and been refused visa issuance at a border post is prohibited from re-admission or re-entry to the United States in the same visa category, even though they are in possession of a valid I-94 form.

我不知道refused visa at a border post 應該怎么理解 是邊防 還是指 邊境城市的領館 不敢給大家誤導 請高手指點
Citizens from State Sponsors of Terrorism countries就不用擔心了 只要你的護照不是北朝鮮 伊朗 敘利亞 蘇丹 古巴就成

我要是回不來 在我衣柜夾層里面有一條紅色的棉褲 褲襠里面縫了一個存折 存折上有100塊錢 大家拿著去吃飯吧。
