To get a Luxembourg Visit Visa, travel insurance is a must. It has to meet Schengen standards. The insurance should cover at least €30,000, be good in the whole Schengen Area, and last for your whole visit. It needs to cover medical emergencies, hospital stays, and getting you back home if needed. Include proof of this insurance with your visa application. Be sure a trusted company issues your policy and that it shows all the needed coverage details.
