Your DS2019 needs to be a PDF, not a photo. If you do not have access to a scanner, we recommend downloading the app "Scanner" to create it as a PDF on your phone.
While we are here to support you, please understand that traveling outside of the country is at your own risk. We encourage you to take all necessary precautions to ensure a safe and successful trip. Please make sure you travel with your passport, signed DS2019, and copies of your I-94.
