Keep yourself up to date with your government's latest travel advice and warnings, right up until you leave.
Make sure you have the correct visas and that your passport is valid - for some countries it must be valid for at least 6 months from the date you enter the country.
Make copies of your passport and other important documents and keep one set with someone at home and another set with you, separate from the originals.
Take some emergency funds in cash and travellers cheques, making a note of the cheques' numbers before you go.
If you plan to drive, make sure your licence is current and valid.
Insurance and healthcare
Wherever you're travelling, you must get travel insurance before you go, making sure it covers you for activities such as extreme or water sports if you think you may participate.
If you're a citizen of the EU, organise your free European Health Insurance Card for access to free or reduced emergency care anywhere within the EU, though you'll still need full travel insurance.
Organise your travel vaccinations at least six weeks before you leave and find out about your destination country's rules on carrying prescription medicines.
Mobile phones
If you're taking your mobile phone, check with your service provider to make sure you'll have access abroad, or think about buying a local SIM card when you arrive.
If you take your phone, store useful numbers such as the local police and your nearest embassy or consulate.
When you get there
Refresh yourself when you arrive with a shower but avoid hot baths as they may make you feel tired.
To minimise your jet lag, try to get out into natural light and eat according to the mealtimes of your new time zone.
Be extra careful with food and drinks so you'll stay fit and healthy for meetings.
Find out whether it's safe to drink local tap water. If not, stick to bottled water, avoid salads, ice and fruit that can't be peeled.
Be vigilant applying insect repellent, especially in the evening, to protect yourself from insect bites.
Be discrete with your valuables, including mobile phones and cameras. You may want to use a padlock on your suitcases and briefcase or handbag.
General advice
Respect the environment of your host country - don't buy wildlife souvenirs, conserve resources like water and don't litter.
Be sensitive when taking photographs, videos or using binoculars. Your intentions may be misunderstood, especially near military installations.
Spend some time finding out about local customs and dress and local laws - there may be serious penalties for breaking laws that to you may seem trivial.
