Medical Visa Guide for Bangladeshis: Invitation Letters, Documents and Timelines

Nearly every treatment-abroad journey runs through one document: the medical visa. Get it right and travel is smooth; get it wrong and surgery dates slip. Here's exactly how it works.

The invitation letter: your starting point

A medical visa needs a hospital invitation letter — issued by the treating hospital once your case is accepted. It states the patient's (and attendants') details, the planned treatment, and the treatment dates. No invitation letter, no medical visa: this is why case acceptance comes before visa application, never after.

Standard document set

Passport valid 6+ months with blank pages; recent photographs per embassy spec.
Hospital invitation letter (original or verified digital copy, per embassy).
Medical summary and the hospital's treatment plan/estimate.
Proof of funds: bank statements and solvency certificate — embassies want to see you can pay for treatment and stay.
Confirmed return flight booking and hotel/stay arrangement.
Attendant documents: proof of relationship and their own invitation reference.

Country notes

China (S2 medical visa): invitation letter plus bank solvency and the facilitator's guarantee letter are standard at the Dhaka mission. Visa fees run roughly BDT 12,000–30,000 depending on entries and processing speed.
Turkey: e-visa or sticker visa depending on category — confirm the correct medical category rather than traveling on a tourist e-visa for surgery.
Thailand: medical visa categories exist for longer treatment stays; short procedures often use standard entries — confirm with the hospital which fits your treatment length.
Pakistan: medical visa on hospital invitation; allow extra processing time and apply early.
Korea: short-term medical stay categories; the hospital's invitation and appointment confirmation are key.

Realistic timelines

From complete documents to visa in hand: typically 5–15 working days depending on the country and season. Build buffer — never book non-refundable surgery-linked travel before the visa is issued.

Common mistakes

Applying before the hospital accepts the case (no invitation letter yet).
Weak proof of funds — the most common refusal reason.
Wrong visa category (tourist visa for surgery) — can cause refusal or entry problems.
Last-minute applications colliding with surgery dates.

How we help

We sequence it correctly: case acceptance → invitation letter → document pack → application → travel. Our document checklist is per-country and current, and we review your file before submission so avoidable refusals don't happen.

Traveling with an attendant

For surgery and transplant cases, a companion is not optional — hospitals expect one, and recovery without help is miserable and unsafe. Attendants need their own visa (usually a medical-attendant category tied to your invitation), their own proof of funds, and proof of relationship. Practical notes: the attendant's passport must be valid just as long; book their return flexibly in case your stay extends; and brief them on the plan — a calm, informed companion is half the recovery.

Frequently asked questions

Can children travel as attendants? Minor children can accompany parents but cannot serve as the responsible attendant for a surgical patient — bring an adult.

What if the visa is refused? Find out the reason in writing, fix the specific weakness (usually funds or documentation), and reapply. A refusal is not a ban — but reapplying with the same weak file wastes time.

Do I need a new visa for follow-up visits? Usually yes, unless your visa is multiple-entry. Factor this into the total plan for treatments needing staged visits.

Key takeaways

No invitation letter, no medical visa — case acceptance always comes before the visa application.
Standard file: passport, invitation letter, medical summary + estimate, proof of funds, return booking, stay proof.
Weak proof of funds is the most common refusal reason — fix the file, then reapply.
Allow 5–15 working days and never book non-refundable travel before the visa is issued.
Attendants need their own visas — bring an adult companion for any surgical case.
