As of early 2021, Dominica has signed visa waiver agreements with 143 countries and territories. It is ranked 34th in the annual passport index. But it is not all about the number of countries.
What also matters is which countries you can visit without a visa and how long you can stay there. Dominica national scan fly to any Schengen state and stay there for up to 90 days. They can also spend up to 180 days in the UK, the former metropole. Since Great Britain is no longer part of the EU, Caribbean citizens can spend the best part of the year in the UK and continental Europe.
