What would you like to know about Singapore's visas and border crossings?
Citizens of most nations enter Singapore for up to 30 days visa-free -- so there's no need to get a visa in most cases -- and 30 days is more than enough to see all the sights you could possibly imagine in Singapore.
Commonwealth citizens may enter Singapore visa-free if they are in transit to a third country, hold a valid passport and onward tickets.
Some nationalities, including the following: Afghanistan, Algeria, Bangladesh, Egypt, India, Iran, the Central Asian states and Russia, Iraq, Jordan, Lebanon, Libya, Morocco, Myanmar, People's Republic of China, Pakistan, Saudi Arabia, Somalia, Sudan, Syria, Tunisia and Yemen are required to get a visa to enter Singapore.
Stays may be extended online via the e-XTEND service (http://www.ica.gov.sg/page.aspx?pageid=179&secid=178). There is a fee of S$40 associated with getting the extension.
Each entry is single entry only. The Singapore entry stamp is a small, quarter page one, and it's no big deal to pop over to Malaysia to get another one, should you need to stay in Singapore longer.
Overstaying your visa in Sinagpore is not encouraged -- especially as you can extend your stay via the service mentioned. At a minimum an overstay attracts a fee of $30.
This is Singapore! -- nothing to watch out for, other than don't overstay.
Departure tax from Singapore's Changi Airport is included in the ticket price so there's no need to hand over cash upon departure.

Singapore has just a couple of overland and sea entry points, with the bulk of foreign tourists arriving by air into Singapore's Changi airport.
Changi airport is by far the most popular arrival point into Singapore. Overland, most arrive (or leave) via the causeway that links Singapore ane Johor Bharu in Malaysia -- this is also the route the train takes. A second causeway links Tuas in the west of Singapore with Geylang Patah in Malaysia -- this a popular route if you're heading to Melaka. For arrival and departure by sea, the most probable routing is to Pulau Batam (for Sumatra) with Pulau Bintan coming a distant second.
Easily the most popular land crossing. The easiast way to cross is catching a bus between Johor Bharu and Singapore -- the trip takes no more than an hour -- including the paperwork at the border. The bus will wait for you while you clear customs and immigration.
The second causeway, at the western tip of Singapore is convenient for travel north up Malaysia's west coast -- if you're heading to Melaka this is likely where you'll be crossing. As with the other causeway crossing, the bus will wait for you while you clear customs and immigration.
Ferries from Batam dock at the Harbourfront Centre, around 5km from downtown Singapore, but close to Harbourfront MRT. Ferries from both Bintan and Tioman Island dock at Tanah Merah Terminal, a busride from Bedok MRT.
