When visiting any country it is prudent for you to know the basic rules of the country you're visiting to avoid any unnecessary violations. In Singapore, it is prohibited to engage in any form of business, profession, occupation or paid employment while on visit passes. If you need to perform these things, a separate pass intended for that should be secured. I think this rule is basic to every country. Another interesting fact about Singapore is that, chewing gums are prohibited here, so don't you dare chew on gums around as you may be fined for that. To be safe, just avoid bringing any of it in your travel here. Also, Singapore is one of the cleanest cities in the world and you will be able to observe that when you finally step down here. One way to maintain its cleanliness is to prohibit littering and spitting anywhere you like. There are litter bins for your garbage and toilets for you to spit. Take note of the warnings you see everywhere so you won't get in trouble. Huge fines will be charged on you if you violate something. And worst, you will be sent to jail or even caned. But if you're a law-abiding person and you act according to what is right, then I think this won't be a problem.
Overall, Singapore is a very nice place to visit, it is not at all scary to come here as this place is a very safe place to visit. It has a lot to offer too and so easy to familiarize with. In fact, this place is highly globalized as you can find people from different races living in harmony may it be locals or foreigners working or just visiting Singapore.
