Most of travel planning is flexible. If your hotel is not ideal or a museum is closed, you can adjust. Documents are different. If your passport or entry permission is not in order, you may not be allowed to board your flight or enter your destination. That is why we always suggest checking documents first.
This guide explains the basics in plain language. It is general information only. Rules vary widely and change over time, so always confirm the details for your own situation with official sources.
Your passport
A passport is your main identity document for international travel. A few things are worth checking early.
Do you have one?
If you have never had a passport, find out how to apply in your country and how long it usually takes. Processing times can vary through the year, and busy seasons may be slower. Applying well before you plan to book a trip gives you breathing room.
When does it expire?
Look at the expiry date on your current passport. Some countries expect your passport to be valid for a certain period beyond the date you plan to leave. If your passport is close to expiring, renewing it before you travel can save you trouble.
Is it in good condition?
A passport that is damaged, for example with water damage or torn pages, may be refused. If yours is worn, consider replacing it.
Do you have enough blank pages?
Some destinations require a certain number of empty pages for entry stamps or visas. If you travel often, check that you still have space.
Visas and travel authorisations
A visa is permission to enter a country for a particular purpose and period. Whether you need one depends on several things:
- Your nationality, as shown on your passport.
- Your destination.
- The purpose of your trip, such as tourism, study or work.
- How long you plan to stay.
For many short tourist trips, travellers from some countries can enter without a visa. Others need to apply in advance. In some cases, an online travel authorisation is required even when a full visa is not. These authorisations are usually applied for online before travel.
How to find out what you need
The most reliable sources are:
- The official government website of your destination country, often its foreign affairs or immigration department.
- The embassy or consulate of your destination in your country.
- Your own government's travel advice pages, which often summarise entry requirements for its citizens.
Be careful with unofficial websites that offer to process applications for a fee. Some are legitimate services, but others charge extra for something you could do yourself on the official site. Where possible, apply through the official government portal.
Transit can count too
If your journey includes a stop in another country, check whether you need permission to transit there. Rules differ depending on whether you stay airside in the airport or pass through immigration, and on your nationality.
Other entry requirements
Some countries ask for additional items at the border. These can include:
- Proof of a return or onward ticket.
- Proof of where you are staying.
- Evidence that you can support yourself during your stay.
- Certain health documents.
You may never be asked for these, but it helps to have them ready, either printed or easy to find on your phone.
Travelling with children
If you are travelling with children, especially if only one parent is travelling or the child is travelling with another adult, some countries and airlines may ask for extra documents such as a consent letter. Check the requirements for both your destination and your departure country well in advance.
Keep copies safe
Losing a passport abroad is stressful, but being prepared makes it easier to handle.
- Save a scan or photo of your passport photo page in a secure place you can access from your phone or email.
- Keep a printed copy separate from your actual passport.
- Note the contact details of your country's embassy or consulate at your destination.
If your passport is lost or stolen, report it to the local police if required and contact your embassy or consulate. They can explain the options for emergency travel documents.
A simple document checklist
Before you book, and again before you leave, run through this list:
- Passport valid for the required period, in good condition, with blank pages.
- Visa or travel authorisation, if needed, confirmed on an official source.
- Transit requirements checked for any stopovers.
- Supporting documents ready, such as bookings and onward tickets.
- Digital and paper copies stored separately.
- Embassy or consulate contact details saved.
Check early, then relax
Documents are not the fun part of travel, but they are the foundation. Checking them early, using official sources and keeping copies safe removes one of the biggest risks from your trip. Once they are in order, you can focus on the parts you are actually looking forward to.
