The core documents for a business trip
A business trip needs the same base documents as a holiday, plus paperwork that explains the purpose of your visit. Start with a passport that meets your destination's validity rule, any visa or electronic authorisation, and proof of where you are staying.
A trip1 booking confirmation covers the accommodation part. It arrives by email as soon as your booking is confirmed and shows the hotel name, address and your dates, which is exactly what a border officer asks for.
- A passport valid for the whole trip, and usually for at least six months beyond your return date.
- A visa or electronic travel authorisation if your nationality needs one for that country.
- Your flight itinerary, including a return or onward ticket.
- Your hotel booking confirmation showing the address and your check-in and check-out dates.
- A letter of invitation from the company or event you are visiting.
- A letter from your employer confirming your job and who is paying for the trip.
Business visa or tourist visa - which one do you need?
Most countries treat business visits and tourism as separate categories, even when both are short. If your nationality needs a visa, you normally apply under a business category, and the supporting documents differ: the consulate wants the invitation, your employment details and often the host company's registration papers.
If your nationality enters visa-free or with an electronic authorisation, you usually still declare a business purpose at the border. An ESTA for the United States, an eTA for Canada and a UK ETA all cover short business visits such as meetings and conferences, but none of them covers paid employment.
Check the destination's official immigration site rather than assuming. Rules differ between neighbouring countries, and some activities that look harmless, such as hands-on equipment installation, are treated as work rather than a business visit.
Invitation letters and employer letters
An invitation letter comes from the company, client or event organiser you are visiting. It should name you, give your dates, describe the reason for the visit and say who covers your costs. Ask for it on company letterhead with a signature and a contact number so an officer can verify it.
An employer letter comes from your own company. It confirms your role, that you are employed and expected back, and that the trip is company business. Two short paragraphs are enough.
Carry both even when you expect nobody to ask. They cost nothing to print and they turn a slow secondary inspection into a short one.
A business visit is not the same as working
You cannot take up paid work for a local employer on a tourist entry or a short business visit. Attending meetings, negotiating and going to a conference are fine in most countries. Being paid by a company in that country, or doing productive work for a local client, normally needs a work permit.
Important: Arriving on a tourist entry and telling an officer you have come to work can get you refused entry and put on the next flight home. Refusals are recorded and can affect future visa applications for years.
Documents your finance team will want
Ask for an itemised hotel invoice at check-out rather than relying on the booking confirmation. The invoice shows the nightly rate, taxes and any extras charged to the room, which is what expense systems and tax reclaim rules usually require.
If your company reclaims VAT on foreign hotel stays, the invoice normally needs the company name on it. Give the hotel your employer's billing details at check-in, not at check-out.
Keep boarding passes, transport receipts and any conference registration confirmation. A hotel may also ask for a payment card at check-in to hold a deposit against incidentals such as the minibar - that is the hotel's own policy and separate from how the room was paid for.
Business travel documents - FAQ
For US travellers, the main changes are in Europe and the UK. The EU's Entry/Exit System, which records your fingerprints and photo at Schengen borders instead of stamping your passport, has been fully operational since 10 April 2026. ETIAS, the EU's travel authorisation, is due to start in the last quarter of 2026. The UK requires an ETA.
It depends on your nationality and the destination. If you can already enter visa-free or with an electronic authorisation, such as an ESTA, eTA or UK ETA, short meetings and conferences are usually covered. If your nationality needs a visa, you normally apply under a business category with an invitation and employment details.
Your name, your travel dates, the reason for the visit and who is paying your costs. Ask the company, client or event organiser to print it on letterhead with a signature and a contact number, so a border officer can verify it. Carry it even if you expect nobody to ask.
It should confirm your job title, that you are employed and expected back, and that the trip is company business, including who is paying for it. Two short paragraphs on company letterhead with a signature are enough. Together with the invitation letter, it turns a slow secondary inspection into a short one.
Ask the hotel for an itemised invoice at check-out, because expense systems and VAT reclaims usually need the nightly rate, taxes and extras listed, not just the booking confirmation. Give the hotel your employer's billing details at check-in. Keep boarding passes, transport receipts and conference registration confirmations too.
No. Attending meetings, negotiating and going to conferences are fine in most countries, but being paid by a local company or doing productive work for a local client normally needs a work permit. Telling an officer you have come to work on a tourist entry can get you refused and put on the next flight home.
