Cambodia eVisa supporting documents are not all the same. Tourist visa files usually prove your stay, funds, and route. Business visa files add evidence from the inviting company, employer, sponsor, or host. Before uploading anything, match each file to the exact slot shown in the official eVisa form.
TL;DR: For Cambodia eVisa, prepare files by purpose, not by filename alone. Accommodation comes from a hotel, host, rental, or company-arranged stay. Bank statements come from your bank. Inbound and outbound tickets come from the airline, bus, ferry, or travel provider. Business invitation, company letters, guarantee letters, patent certificates, and hiring quota documents come from the Cambodian host company, employer, sponsor, or HR team. Upload only what the current official form asks for your visa type.
Tourist vs Business File Map
| File shown in the form | Usually for | What it proves | Where it normally comes from |
|---|---|---|---|
| Accommodation | Tourist and Business | Where you plan to stay in Cambodia | Hotel, booking platform, host, rental provider, or host company |
| Bank statement for the last 3 months | Tourist and Business when requested | You have funds for the trip | Your bank, online banking app, or branch |
| Flight or bus ticket in | Tourist and Business | How and when you enter Cambodia | Airline, bus company, ferry operator, or travel agency itinerary |
| Flight or bus ticket out | Tourist and Business | Planned departure or onward route | Airline, bus company, ferry operator, or travel agency itinerary |
| Other files | Case-specific | Extra proof requested by the form or officer | Depends on the request: itinerary, explanation letter, relationship proof, or extra booking |
| Letter of invitation | Business | Who is inviting you and why | Cambodian company, organizer, customer, school, NGO, or host |
| Patent certificate | Business | The inviting Cambodian business has local registration or tax standing | Cambodian host company or its finance/admin team |
| Business or company supporting letter | Business | Your role, employer, trip purpose, and dates | Your employer, your own company, or the sending organization |

| Hiring quota | Employment-linked Business cases | The Cambodian employer has authorization or quota for foreign hiring | Cambodian employer or HR/legal team |
The names in the official upload form can change. If a slot is marked required, do not skip it. If a slot is optional and does not fit your trip, do not upload unrelated files just to fill space.
Accommodation
Accommodation is the file that connects your visa application to a real stay address in Cambodia. For a tourist trip, this is usually a hotel booking confirmation, guesthouse confirmation, apartment booking, or letter from a host.
For business travel, accommodation may come from the hotel, the Cambodian host company, or an event organizer. The useful details are the traveler's name, property or host name, address in Cambodia, check-in and check-out dates, and booking reference if available.
Use a PDF or clear image that shows the stay details. Do not upload only a map pin, chat message, or screenshot with no traveler name or dates unless the official form specifically accepts it.
Bank Statement
A bank statement is used to show that the traveler has enough funds for the planned trip. In the current Cambodia eVisa form, the tourist support-document list can ask for bank statements for the last 3 months.
You normally get this from:
- online banking, downloaded as PDF;
- a mobile banking app export;
- a bank branch statement;
- a stamped statement if your bank or local practice requires it.
Before uploading, check that the statement belongs to the applicant, covers the requested period, and is readable. If you need to hide unnecessary transaction details for privacy, keep the name, bank identity, statement period, and balances visible enough for the document to make sense.
Inbound Ticket
The inbound ticket proves how you plan to enter Cambodia. It can be a flight to Phnom Penh, Siem Reap Angkor, Sihanoukville, or another route that matches the eVisa entry plan. For land or regional routes, the form may refer to a bus ticket.
The file should come from the airline, bus operator, ferry operator, booking platform, or travel agency itinerary. It should show the traveler's name, route, date, and booking reference if available.
Do not use a generic route search result as a ticket. If your route depends on a land border, also check whether the port is selectable in the current eVisa form.
Outbound Ticket
The outbound ticket shows your plan to leave Cambodia or continue to another country. It may be a return flight, onward flight, bus ticket, ferry booking, or other confirmed transport.
This file matters because it connects the trip length, visa type, and stay plan. Before uploading, compare the departure date with the intended entry date, hotel dates, and visa validity shown by the official application flow.
If you do not yet have a confirmed outbound booking, stop and check the current official requirement before paying. Do not invent a ticket or edit a document.
Letter of Invitation
A letter of invitation is common in Business visa cases. It explains who is inviting you to Cambodia, why you are visiting, the planned dates, and who the contact person is.
It usually comes from:
- a Cambodian company;
- a customer or business partner;
- a conference or event organizer;
- a school, NGO, or institution;
- another host that can explain the business purpose.
A useful invitation letter should normally include the applicant's name and passport number, inviter name, company or organization details, address, contact person, purpose of visit, expected dates, and signature or company stamp if the host uses one.
Patent Certificate
In Cambodia business-document language, a patent certificate usually means a business registration or tax-related certificate connected to the Cambodian company. The traveler usually does not create this document.
Ask the Cambodian host company, sponsor, or organizer for it. The file should identify the company and should match the company named in the invitation letter or supporting letter. If the company cannot provide it, ask what alternative document the official form or consular channel accepts before uploading something unrelated.
Business or Company Supporting Letter
A business or company supporting letter is different from an invitation letter. The invitation letter normally comes from the host in Cambodia. The supporting letter often comes from the traveler's employer, own company, or sending organization.
It should explain:
- who the traveler is;
- the traveler's role or job title;
- why the trip is needed;
- the travel dates;
- who pays for the trip if that matters;
- how the trip relates to the Cambodian host or event.
For self-employed travelers, the letter may need to come from the applicant's own company and be backed by registration, contract, or client evidence if the form asks for it.
Guarantee Letter
A guarantee letter is a sponsor or host statement. It may explain that the host, employer, organizer, or sponsor is responsible for the traveler's stay, costs, accommodation, or business activity during the visit.
This file should come from the party making the guarantee. It is not the same as a traveler's personal explanation. Check that the guarantor's name, company, address, contact details, and relationship to the applicant are clear.
Hiring Quota
Hiring quota documents are relevant when the business case is connected to employment or a Cambodian employer's ability to hire foreign workers. Most short meeting or conference visitors will not create this document themselves.
If the upload slot appears for your case, ask the Cambodian employer or HR/legal team. The document should come from the organization that is hiring or sponsoring the work-related activity, not from the traveler.
Upload Checks Before Payment
Before paying or submitting, check each file:
- the applicant name matches the passport;
- the passport number, if shown, is correct;
- dates match the intended entry date and trip length;
- the company or host name is consistent across letters;
- the file is readable after upload preview;
- the format and size match the official form limit;
- no document belongs to the wrong family member or client;
- you are still using the official Cambodia eVisa portal.
For a family, group, or agency, use one folder per traveler. Do not keep all bank statements, tickets, and hotel files in one shared download folder with vague names.
If You Handle Several Travelers
Document collection still needs human judgment: the traveler, host company, employer, or agency must decide which files belong in each upload slot. But the repeated form fields around those files are predictable.
If you prepare Cambodia eVisa or e-Arrival details for yourself, family members, or clients, eVisaFlow Cambodia can fill saved passport, trip, stay, and contact details on the Cambodia eVisa and e-Arrival official websites after you run the extension. Keep the document review separate from the form-filling step: each uploaded file still needs to match the official slot and the current traveler.
