» Never carry with you or get involved in drugs, no way. Penalties are severe: from 10 to 50 years in prison or even a death sentence. Also, check that your medical prescriptions are legal in Thailand.
» For extended stays or when security circumstances are not stable, it is advisable to register at your country’s embassy in Bangkok or the local consulate.
» Beware of pickpockets when visiting crowded tourist spots.
» Keep your passports safe, often stolen. Never leave your passport as bail when renting a motorcycle or a car. If you decide to keep it in the safety box of your hotel, take a copy with you.
» In the event of an incident, as it could be a robbery, request the first aid to the tourist police (1155), present in the tourist areas of the country.
» Be careful when riding a motorbike because driving this vehicle in Thailand may be dangerous, especially at night, when the alcohol shows up, as well as during the rainy season. Never discard the helmet, which often happens among Western visitors.
» Regarding scuba diving, keep in mind that this is a risky activity and, therefore, you must find a specialised company with the most demanding standards.
» Never go through a customs office with something that doesn’t belong to you.
» Upon arrival on your international flight, verify that your passport has the entry stamp once you have passed the immigration counter and do not lose or damage the immigration card. Take a photo with your mobile.
» Do not accept the help of the local guides that are offered on the street, even if they show apparently right credentials.
