Passport Validity

Your passport must be valid on entry into the U.S. If the passport is not valid for the duration of your stay, you will be required to apply for a new passport from your Embassy while in the U.S. If your visit will be of short duration during which time your passport will expire, we recommend that you obtain a new passport before traveling as you will be admitted only until the date on which the passport expires. Such action before you depart for the U.S. will save you the inconvience of applying not only for a new passport, but also an extension of stay.

Citizens of the countries listed here are exempt from the six-month rule and need only have a passport valid for their intended period of stay.
