Question: do i need a visa to visit paris from trinidad and tobago?
Answer: It seems clear enough: "Trinidad and Tobago citizens do not need a visa to travel to the Schengen area and to the French overseas departments and territories for short stays (up to 90 days)". France is a Schengen Area country, and so, as Trinidadian passport-holders, you do not need a visa to visit Paris for 3 days.
