Every destination asks for the same kind of file, in a different order, for a different lane. This page is the master checklist: what every hospital needs, how the invitation letter works, and what slows cases down — before you open any destination-specific guide.
Most destination countries need a medical visa supported by a hospital invitation letter. The hospital issues the letter once your case is accepted; we guide the paperwork end to end. Timelines run from a few days to two weeks depending on the country. Plan your documents with the visa timeline planner in our tools.
Three things, all avoidable: incomplete records, records that do not match the hospital's required standard, and starting the visa before the case is accepted. We reformat everything to the hospital's standard so nothing bounces back, and we keep the order right — case review first, invitation letter second, visa third.
Do I need a medical visa for treatment abroad?
Most destination countries need a medical visa supported by a hospital
invitation letter. The hospital issues the letter once your case is accepted;
we guide the paperwork end to end.
Who arranges the invitation letter?
The hospital, once your case is accepted. We guide the paperwork end to end
— but the letter follows acceptance, never the other way round.
How long does the visa step take?
Timelines run from a few days to two weeks depending on the country. A
complete file moves fastest; an incomplete file comes back with questions.
What if my records are old or incomplete?
We tell you exactly what is missing before anything is submitted, so you fix
it while you are still in Dhaka — not after you have travelled.
Where do I find my destination's specific documents?
In the per-destination guides: Pakistan, China, Turkey, Korea, and Thailand
each have their own visa-and-documents page, because each lane reads a
different file.
Archon also arranges trip arrangements, accommodation and transportation for patients — in any country. Your contract for treatment is with the hospital, not with us and not with any agent. We coordinate; the hospital treats and bills.
