When applying for a multi-year Russian business visa you have to provide a letter of proof that says you have travel medical insurance for the visa validity period, which in this case can be for two or more years. Finding travel medical insurance that is valid for multiple years is easy in for example Europe. But where can multi-year travel medical insurance be found in the United States that will allow getting the required letter of proof?
Most major U.S. insurance companies only seem to provide single trip or one year travel insurance, but not for multiple years at a time.
