To verify the identity of each applicant and to ensure accuracy of personal information, you must include a copy of the personal information page of your passport.
Please make sure that your name, place of birth, date of birth, and other details are completely legible on the passport copy. A passport copy is sometimes faded and difficult to read, especially after having been copied or faxed.
Passports need to be valid up to six months after the date of your intended departure from the United States. For example, if you plan to remain in the U.S. through June 2017, your passport must be valid until at least December 2017.
