Conclusion

The invitation letter for a Schengen visa is one of the crucial documents that are required to support the visa application and greatly enhance the chances of getting a visa to visit a family member, friend, or to attend a business meeting or medical treatment within the Schengen Area. You need to write a letter by a legal resident or citizen of a Schengen country that contains your full personal details (passport number, date of birth, address), the host's details, exact dates of travel, a detailed itinerary and a clear financial capacity statement, detailing who will be paying for the trip. The letter assists in your application, but does not replace the other visa requirements, which you are required to satisfy.

The letter, written by the host, and professionally and concisely worded (one page) and signed and dated by the host, with all details as per other visa documents, plus supporting documents (host's ID, proof of accommodation, relationship evidence, etc.), will make a difference in getting a visa approval or rejection. Each country has its own requirements (e.g., in France the Attestation d'Accueil, in Germany the Verpflichtungserklärung), so please check the embassy's requirements for each country before submission.
