Prepare the F exchange / visit route around a complete invitation letter
What this page solves
F visa · Exchange / visit
This page is the working path. Prepare the real files, request missing documents, clear the readiness conditions, jump to the problem you are facing, and use the official owner only for the final authoritative step.
Resolved here: what route to use, what to get, who to ask, what to say, what “done” looks like, and what to do when something goes wrong. Still external: a school/employer/inviter issuing their document and the authority accepting the final application.

01Problem 01
The invitation just says “visit our institution”

Problem not listed?
Describe the blocker and turn it into a precise clarification request
Use this when your case does not match the scenarios above. The goal is not to guess the answer — it is to ask the responsible owner for the exact missing condition, document or route.
02 · Prepare the files
Get the actual documents ready
The real-world photo above shows the task context. The cards below tell you what each file is for and what to check. Example PDFs are secondary references only — not official templates.
Your current travel documentBasic identity / travel document.
Identity must match the invitation and application.
Use the same passport or travel document you will actually present for the trip. Check the expiry, document type and identity details before using any booking or invitation made from it.
Chinese inviting institution / personCore F-visa supporting document.
Include invited-person details, purpose, dates, places, relationship, payer, inviter contact details and signature / entity seal as applicable.
Ask the Chinese inviting institution or person for a complete invitation before you submit the visa file.
Could you please issue a signed invitation for my China visa application showing my full name and passport details, the exchange / visit purpose, dates, places and activities, who pays the trip, your contact details, and the authorised signature / organisation seal where applicable?
Airline / booking providerSupports the dates and visit plan.
Keep it consistent with the invitation.
Download the current itinerary receipt from the airline or booking provider. Use the version that shows the traveler name, route and dates, not only a booking-app screenshot.
03 · Ready-to-proceed gate
Do not continue until these conditions are actually true
This is not a generic task list. It is the final readiness gate: each checkbox means one real blocker has been removed. If a box is still unchecked, that tells you exactly what is still missing before you submit, travel, or rely on this route.
Stops you from moving forward with a route that still has an unresolved document, date, category or owner confirmation.
Only tick a row after the named result exists in your hands or has been confirmed by the responsible party.
When every row is ready, the page has reduced the problem to the one external step it cannot perform for you: the authoritative application or admission decision.
Readiness result
You still have unresolved conditions
Unchecked rows are not reading reminders. They are the exact document, date, category or owner confirmations that still block you from safely moving on.
04 · Final authoritative step
Now open the official owner with a specific job to do
You should already know the visa route, files and problem you are resolving. These links are for the authoritative rule / application step — not for restarting your research from scratch.
Use the F Visa section.
Use after the invitation is complete.
