Visas: Bureaucratic hassles will be your first problem in getting a visa - expect delays of five days or more; Bangkok is the best place to get one. It's usually best to get your visas through a travel agency. Expense is the other problem; tourist visas valid for a single 30-day stay cost about US$40 in Bangkok.
Health risks : Dengue fever, hepatitis, malaria, rabies (if in the country for a month or more), typhoid and tuberculosis (if staying with locals in a high risk area for a few months or more)
Electricity: 220V and 50Hz, but 110V (also with 50Hz) may be encountered
Weights & measures: Metric with local variations.
