| Quick Answer Before travelling internationally, check that your passport is valid for at least six months past your return date, confirm whether you need a visa or an electronic travel authorisation, get travel insurance, register with your government’s traveller programme, check vaccine requirements, arrange how you’ll access money abroad, and make copies of your key documents. Doing these steps two to four weeks ahead avoids most last-minute travel problems. |
Knowing what to do before travelling internationally can save you from unexpected delays, costly mistakes, and travel stress. Booking a flight is only the first step—properly preparing for your trip by checking passport validity, visas, and health requirements ensures a smooth and hassle-free journey.
This is a list of things to do to prepare for a trip, written in everyday English to help you avoid those common travellers’ pitfalls.
1. Check Your Passport Well in Advance
This is one mistake most people tend to make while traveling. The most common mistake that you must avoid is making sure that your passport is valid for at least six months after your departure. The most countries require that your passport must be at least six months valid after their departure even if your journey is shorter. You would need a new passport if your present passport expires in less than six months. It can take eight weeks or more to renew your passport, which is not a period to take lightly.
What to do: Check your passport’s expiration date, and if it is within six to eight months of your trip, renew it.
2. Find Out If You Need a Visa or Travel Authorisation
Visa requirements can trip up more people than you think, partly because they are subject to change constantly. The UK will be requiring most visitors to have an Electronic Travel Authorisation, and the EU is planning similar ETIAS checks for later in 2026. Both are separate to a visa, but ignoring them could still see you denied entry.
What to do: Search the country you plan to visit by name on your country’s government official travel website before making any arrangements. The entry requirements should be clearly listed and is a quick check in any case.
3. Sort Out Travel Insurance Before You Fly
This one gets overlooked constantly due to the assumption that your typical domestic health insurance will cover you abroad – it almost never will. Most, if not all domestic health care plans, including Medicare, cease coverage as soon as you leave the country while a medical evacuation abroad would easily set you back $100,000 or more in out-of-pocket expenses.
What to do: Purchase a travel insurance package that covers medical treatment, as well as emergency evacuation and trip cancellation or interruption. Know the fine print.
4. Register With Your Government’s Traveller Programme
If something were to go wrong abroad, whether it’s a natural disaster, a civil war, or you have an emergency of your own making, it helps greatly if your embassy knows that you’re there. Programs like the U.S.A.’s Smart Traveler Enrollment Program are free and only take a few minutes of your time.
What to do: Sign up before you leave. It will notify you of any potential safety issues in your area of the world and also makes it easier for embassies to contact you, should the need arise.
5. Check Vaccine and Health Requirements
Some destinations require proof of specific vaccinations before you’re allowed to enter, and others simply recommend them for your own safety. This varies a lot by country and even by region within a country, so it’s worth checking properly rather than guessing.
What to do: Check current guidance for your destination and speak to your doctor or a travel clinic several weeks before departure, since some vaccines need time to become effective.
6. Plan How You’ll Access Money Abroad
Turning up at the airport with no plans for cash could be a problem, as airport currency exchange counters tend to offer poor rates. It’s also a good idea to let them know you’re going to be abroad with your card, to avoid your bank account freezing up due to ‘suspicious’ international transactions.
What to do: Withdraw cash from a bank/atm after arrival, bring a second card for backup, and let your bank know in advance that you’re going to be using it overseas.
7. Make Copies of Your Important Documents
Losing a passport abroad is stressful enough without also having no proof of who you are or what your travel plans were. A simple set of copies makes the entire replacement process faster.
What to do: Make both physical and digital copies of your passport’s photo page, visa, and itinerary. Leave one copy with someone at home, and keep another separate from the original while travelling.
8. Check Local Laws and Medication Rules
What is perfectly legal to possess at home may be illegal overseas. Some countries have very strict regulations about medication – both regular medications and CBD products. Despite being legal in many states in the US, CBD meds can get you in a lot of trouble elsewhere.
What to do: Do some research ahead of time as to what the policies are in the country you are visiting. Keep your medications in their original containers in your carry-on bag with a copy of the prescription you used to fill them.
9. Pack Smart for Power and Connectivity
It’s a small thing that causes a surprising amount of frustration — arriving somewhere and realising your charger doesn’t fit the wall socket. Different regions use different plug types and voltages.
What to do: Buy the correct adapter (and a voltage converter if needed) before you leave, and consider an international phone plan or eSIM so you’re not stuck without data on arrival.
Key Takeaways: What to Do Before Travelling Internationally
- Passport rules trip up more travellers than anything else — check the expiry date months ahead
- Regular health insurance rarely covers you abroad, so travel insurance really matters
- Visa and entry rules change often, so check the official government site, not a forum post
- A little planning around money, medication, and documents avoids most trip stress
Frequently Asked Questions
How far in advance should I check my passport before travelling?
Check it as soon as you start planning your trip, ideally at least six months before travel, since many countries require six months of validity beyond your return date and renewals can take weeks.
Do I need travel insurance for every international trip?
It’s strongly recommended for every trip, since most domestic health insurance plans, including Medicare, don’t cover medical costs overseas, and emergency evacuations can be extremely expensive.
What is the Smart Traveler Enrollment Program?
It’s a free U.S. government programme that sends safety alerts about your destination and helps the nearest embassy contact you or your family in an emergency.
Can I bring my regular medication when travelling abroad?
Usually yes, but rules vary by country, so it’s worth checking in advance. Keep medication in its original packaging with a copy of the prescription, and carry it in your hand luggage.
Is currency exchange at the airport a good idea?
Generally no. Airport exchange counters usually offer weaker rates and higher fees than withdrawing local currency from an ATM after you land.
