The WorldTrips Atlas International is a single-trip Travel Medical plan available to U.S. and non-U.S. citizens who are traveling outside of their home country (but not within the U.S.). This plan offers up to $2,000,000 medical coverage.

Within minutes after you purchased this policy back on July 25, 2018, Tokio Marine would have emailed your policy with instructions on how to view and print your embassy letter. Unfortunately that letter would have shown the 250 USD deductible which would not have been acceptable for the Schengen Visa.
