Certain entry requirements apply for Singapore, regardless of country of citizenship. A passport that's valid for six months, confirmed airline tickets with entry and exit from Singapore, a valid entry to the next destination, sufficient funds for expenses, and, in some cases, a visa. Travel restrictions are in place for people with HIV/AIDS.
U.S. citizens are required to present a valid, government-issued passport for entry into Singapore. The passport application can be made at a valid passport acceptance facility in the United States. Often, a local post office is a valid passport acceptance facility. Documents required for a passport include proof of citizenship in the form of a birth certificate or certificate of citizenship, current and valid government issued identification, such as a driver's license or military identification, and all applicable fees. Any individual with a passport set to expire within six months of a trip to Singapore will be required to renew her passport before traveling. Singapore, as is the case with many neighboring Asian countries, requires all U.S. travelers to have six months remaining on their passports.
U.S. citizens visiting Singapore for less than 90 days don't need a visa. Those who intend to stay longer, or to pursue full-time studies or employment, will need to apply and be approved for a visa. The Student's Pass is required for those seeking education in the country. A local sponsor is required for the application's approval. For those seeking employment, the Employment Pass is necessary. Applications can be made through the mail or at your nearest consulate or embassy. Processing time can take up to two weeks, regardless of method.
