Before you leave, check if you have a valid airline, train or bus ticket. If you are not sure, call the company or the travel agency. The ticket is usually with a reference or booking number as well as the contact information of the issuing agency. This number will be used in checking the validity of the tickets.
Take note if there are multiple flights or train rides – that is, the travel is not direct from your country to the country where you will work. Take note of the time differences as well as the lay-over time of each step in the travel. Arrive early so that you will not rush.
