You will need to ensure you have a valid passport for your dates of travel, and to enable you to make a visa application.
If you do not have a Passport you will need to apply for one.
Make sure your application can be processed and your passport issued in plenty of time to enable you to comply with any visa application timeframes.
If your passport is in the final year of validity you are advised to check the requirements of all the countries you plan on travelling to before making final travel plans. Some countries impose a minimum passport validity of three, six, or nine months for arriving passengers.
