What should American know before going to Singapore?

Singapore is clean, safe and easy to enjoy. It is also strict, and that surprises many visitors.

This first-time Singapore travel guide covers what Americans should know before going to Singapore, using official sources. Read it once and you will skip the common mistakes.

1. You Do Not Need a Visa for Short Trips

The good news first. The US State Department says no visa is required for stays of 90 days or less. Some sites online say 30 days, but the State Department page says 90.

2. Check Your Passport Before You Book

Singapore entry requirements for US citizens come down to three things: a valid passport, proof that you will leave, and the arrival card. The passport rule catches people out. The State Department says your passport needs 6 months of validity beyond your departure date, plus one blank page per stamp. ICA, Singapore’s immigration authority, sets a minimum validity of 6 months. To be safe, count from the day you plan to leave.

Also carry proof that you will leave. ICA says short-term visitors should have enough cash and proof of onward travel.

3. File the SG Arrival Card (It Is Free)

All visitors need this digital form. You must complete the SG Arrival Card no more than 3 days before you enter Singapore, and it costs nothing. The 3 days include the day you arrive.

Use only ICA’s website or the MyICA app. ICA does not endorse paid services that file it for you. If a site asks for money, it is not the official one.

4. Always Carry Your Passport

Leave the “I’ll just bring a photocopy” habit at home. Police may take you in for questioning if you do not have your passport with you.

5. Learn the Singapore Tourist Rules That Surprise Americans

Singapore is safe, but the laws are tougher than in the US. The State Department rates Singapore Level 1, “exercise normal precautions,” and warns that even mistakes can lead to arrest, deportation or caning. Remember these:

Vapes are illegal. You cannot possess, buy or use vapes and e-cigarettes. An ICA notice says penalties rose on 1 September 2025, and short-term visitors who re-offend face a ban on re-entering Singapore. Leave yours at home.
Drugs mean severe penalties. These include the death penalty or caning.
Public drinking has limits. Drinking alcohol in public places is illegal from 10:30 pm to 7:00 am. Geylang and Little India are Liquor Control Zones with stricter weekend rules.
Small things count. Jaywalking, littering and spitting can lead to arrest.
Gum is a no. Singapore Customs bans chewing gum imports, except dental and medicinal gum approved by the Health Sciences Authority.

Yes, the gum story is true. No, nobody is joking.

6. Check Your Medicines Before You Fly

Americans often pack prescriptions without thinking. Check first. Singapore’s Health Sciences Authority (HSA) says you may need approval before bringing medicines, depending on the active ingredients. Medicines with controlled substances need approval in advance.

If your medicine meets HSA’s criteria, you can bring up to a 3-month supply without prior approval. Keep medicines in original packaging, and carry your prescription or a doctor’s letter. Ask your doctor or check HSA’s site if you are unsure.

7. Buy Travel Insurance (Your US Plan Probably Will Not Help)

Healthcare costs real money here. Medical care is not free in Singapore, and Medicare and Medicaid do not cover bills abroad. The State Department strongly recommends insurance that covers medical evacuation.

Traveling with kids? Children also need an SG Arrival Card. Bring each child’s birth certificate, and a notarized consent letter if only one parent travels.

8. Pay With Your Phone or Card

Money is simple. The currency is the Singapore dollar, ATMs accept US-issued cards, and credit cards are widely accepted. You must declare more than S$20,000 in cash when you enter or leave.

On the train, tap in and out. Foreign Visa and Mastercard contactless cards and mobile wallets work for fares, with no registration. The Singapore Tourist Pass is the other option. Here is how they compare:

	Contactless card or phone	Singapore Tourist Pass
How you pay	Tap your own Visa or Mastercard. No registration.	Buy it at a SimplyGo ticket office, service centre or kiosk.
Cost	You pay per ride.	S$17 for 1 day, S$24 for 2, S$29 for 3, S$37 for 4, S$45 for 5.
Covers	Trains and buses.	Trains and basic buses. It excludes premium services like the Sentosa Express.
Watch for	Ask your bank about foreign transaction fees.	Fixed price per day, so count your rides first.

Tipping: Singapore does not expect tips, including for taxis. Restaurants and cafés usually add a 10% service charge. That is a relief for any American who does tip math at dinner.

Shopping refund: Tourists can get some GST back. You need to spend at least S$100 including GST, and you can combine up to three same-day receipts from the same retailer. Show your original passport at the shop, not a photocopy. Claim at the eTRS kiosks when you leave through Changi or Seletar Airport. See the Singapore Customs guide.

9. Plan for the Weather, the Time Gap and Your Chargers

Weather: Expect hot, tropical weather all year, usually 25–35°C (77–95°F). Heavy rain and flash floods are common from November to January, and haze from regional forest fires can hit between June and October. Pack light clothes and an umbrella. Bring a scarf too, since indoor air conditioning can feel icy.

Time: Singapore does not use daylight saving time. It runs 12 hours ahead of Washington, D.C., during Eastern Standard Time. Expect jet lag, and go outside in daylight on day one.

Power: The CIA World Factbook lists Singapore at 230 V and 50 Hz with type G plugs. That differs from US outlets, so pack an adapter. Check your device label for its voltage range before you plug in a hair dryer.

Water: Tap water is generally safe to drink. Bring a refillable bottle.

10. Stay Alert, Even in a Safe City

The State Department says Singapore is generally safe and crime against foreigners is rare. It does warn about scams, including romance scams, fake officials and lottery or inheritance notices. Ignore any call or message that demands money.

Save these numbers:

Police: 999
Ambulance and fire (SCDF): 995
US Embassy Singapore: +65-6476-9100

Before you go, enroll in the Smart Traveler Enrollment Program (STEP) to get embassy alerts.
