What's a hospital invitation letter?
A formal letter from the destination hospital on official letterhead, signed by the treating doctor, confirming: diagnosis, recommended treatment plan, estimated length of stay, and a cost estimate. Required for most medical visas. Hospital issues it after reviewing your medical records + confirming surgery date. We handle the request/translation/stamping coordination — you don't need to deal with the hospital directly.
This answer is general information, not medical advice. Your own doctor should confirm what applies to your case.
