Report your Visa Lost/Stolen to the U.S. Embassy Abroad Fax the Consular Section or Consul General at the Embassy abroad which issued your visa, to report it lost/stolen. Specifically state whether the visa was lost or stolen. Be sure to include your full name, date of birth, place of birth, address in the U.S., and an email address (if available). If you have a copy of the passport or visa, fax this to the Embassy or consular section. Otherwise, if known, report the category of visa, and the passport number from the lost/stolen visa. If you have already reported your visa lost/stolen to the U.S. Embassy abroad, and then you later find your misplaced visa, please note that the visas will be invalid for future travel to the U.S, and you must apply in person at the Embassy or Consulate abroad for a new visa. Applying for a Replacement United States Visa Lost/stolen U.S. visas cannot be replaced in the United States. For replacement of a visa, you must apply in person at an Embassy or Consulate abroad. When applying for the replacement of a visa, you will need to provide a written account documenting the loss of your passport and visa. Include a copy of the police report.
