我查到的是这样的: Travel to Canada or Mexico The “automatic extension of validity” provision allows most H-1B workers to reenter to the U.S. without a valid H-1B visa stamp after a trip to either Canada or Mexico that lasts no more than 30 days. Automatic revalidation is not applicable to nationals of countries identified by the U .S. as state sponsors of terrorism. For a list of these countries, go to http://www.state.gov/j/ct/list/c14151.htm. While F and J nonimmigrants can use automatic revalidation to re-enter the United States after trips to the Caribbean, H-1B workers cannot. H-1B travel under this provision is limited to Canada and Mexico. To take advantage of this provision, the following must be true: The visit to Canada or Mexico is for 30 days or less. Your passport must be valid for at least six months from your date of re- entry to the U.S. You must possess your I-94 card, which shows an unexpired period of initial admission or extension of stay. You must possess your H-1B approval notice (bottom left side of I-797). You must apply for readmission within the authorized period of initial admission/extension of stay. You must have maintained and intend to resume your nonimmigrant status. You did not apply for a new visa stamp while in Canada or Mexico. Please remember when exiting the U.S. that you should not surrender your I- 94 card; you will need it to re-enter under the provisions of automatic revalidation. Note that automatic revalidation applies only when re-entering the United States. You may need to obtain a Canadian or Mexican visa stamp to enter Canada or Mexico. NOTE: Any non-immigrant who applies for a new H-1B visa in Canada or Mexico and is refused a new H-1B visa, or has an application for a new H-1B visa pending, will not be able to re-enter the United States. When applying for a visa stamp in any country, there is always a risk of being delayed for security clearance.
