Singapore

It is not a visa, and paid lookalike submission sites are unnecessary. On MRT trains and public buses, a foreign contactless American Express, Mastercard or Visa can be tapped directly without an app or account. Foreign Mastercard and Visa cards currently incur a S$0.60 administration fee per day of use, and you must tap in and out with the same physical card or the same phone or watch. Cards work widely elsewhere, but many hawker stalls accept only cash or Singapore-linked QR payments, so carry small Singapore-dollar notes.

English is the common language. The climate is hot, humid and prone to sudden heavy rain, so myENV alerts are more useful than a generic daily forecast. Singapore applies strict laws: vaping products are illegal, controlled medicines may need prior approval, and smoking is banned in many indoor and outdoor places. Call 999 for police and 995 for fire or a life-threatening medical emergency.
