A checklist of other things that need to be considered:
On the home front, make sure all bills are paid or have a means of being paid. If you are retaining a residence while abroad, make sure the rent/mortgage is taken care of and that utilities are being paid for while you are away. Insure that important institutions, like your bank, can reach you.
If you are retaining a bank in your home country, ask about fees for overseas transactions. If you have a credit card, find out if there are additional fees or any changes you need to make to your account. Inform the banking industries that you will be abroad, so as to not arouse suspicious activity on your account as anti-theft systems can see this activity and put a most inconvenient hold on your account.
It is best to inform tax offices of any change in residence. Some countries have reciprocal tax agreements, and others may require you to pay some form of tax both in your home country and aboard. Most National Tax Administrations are an excellent resource for detailing exactly what steps have to be taken when moving away. For more information, refer to our section on taxes.
Nationals from different countries around the world, wishing to reside in Sri Lanka, should refer to their respective Income Tax Departments for details of how to manage their taxation payments and National Insurance contributions in their home countries while they are living abroad.
For concerns about your health when abroad, the World Health Organization (WHO) publishes International Travel and Health, which is revised annually and is freely available online. Another excellent resource is MD Travel Health. It provides free, complete travel-health recommendations for every country and is updated daily.
For entry into Sri Lanka, usual childhood vaccinations are required, along with those for water-borne diseases like typhoid and cholera. It would be prudent for travellers to carry cotton clothing with long sleeves to protect against mosquito bites and dengue fever. A mosquito repellent and sunscreen lotion are also called for.
