信息 -- 签证及身份问题

简而言之：只要你有有效的美国签证，那么去墨西哥就不需要签证。如果你不是绿卡或公民，那你更应关注如何回到美国来。

 

F1 visa。刚在网上查到的， 几天前才贴上去的。

You need your passport containing the valid F-1 visa for the United States and a migration form (FMM, also known as tourist card) if you plan to travel beyond the border zone. Holders of valid U.S. visa are exempt from the visa requirement for Mexico, regardless of their nationality. The FMM will be issued by the airline if you fly, if you cross the land border you will buy it on entry (~$20).

To return to the United States from Mexico you will also need to have your SEVIS-form I-20 endorsed by your Designated School Official stating that you are in good progress with your studies.

F1 Visa Travel to Canada, Mexico, and the Caribbean

If you are traveling only to Canada, Mexico or the Caribbean (except Cuba and Bermuda) for fewer than thirty days, you may return to the U.S. with an expired F-1 entry visa in your passport. To qualify for this privilege, you must:

1. Be in lawful F-1 status.
2. Have an unexpired I-94 card indicating your F-1 status in your passport when you enter the U.S. Do not surrender the I-94 card when you leave the U.S. If you do, you will not be eligible for visa revalidation.
3. Have a current, recertfied I-20 in your possession.
4. Have a passport valid at least six months into the future on the day you return to the U.S.
5. Travel only to one of the destinations named above and for fewer than thirty days. For example, you cannot use automatic revalidation to enter Canada, depart to another country, return to Canada, and then return to the U.S. within 30 days.
6. Not apply for a U.S. visa while in Canada, Mexico, or the Caribbean. If you apply for a U.S. entry visa during your visit to one of these destinations, you must wait for it to be issued before you return. If your visa application is denied by the American consulate, you are not allowed to use automatic revalidation to return to the U.S. You will be required to travel to your country of citizenship to apply for a new visa.
7. Have a F-1 visa (expired or valid) in your passport or an approval notice for change of status to F-1 and the invalid visa of your previous non-immigrant status in your passport.
8. Be a citizen of a country other than Syria, Iran, Iraq, Sudan, North Korea, Cuba, or Libya. Nationals of these countries are not eligible for visa revalidation. If you are a national of one of the above countries, you must always have a valid visa in your passport to enter the United States.
