When travelling to Thailand, there are several important documents, papers and cards that one must carry with them. First and foremost, make sure that you have your passport – it goes without saying that without this particular item, your international travel plans simply will not take place. If you require a visa to enter Thailand, make sure you get it in advance unless your nationality allows you to obtain a visa upon arrival. It is also useful to have identity papers such as a Driver's License in addition to your passport. Travellers should also have their boarding passes (at least the electronic versions saved on their phones), a printed itinerary in the event one is asked for as well as a debit card and a credit card. It would also be useful to have photocopies of these documents ready just in case.
