This may seem like a given, but it is possible to lose track of the necessary travel documents needed to enter Singapore without a hassle. The most obvious document to have is your passport which must remain valid for at least 6 months. Additionally, you’ll need to check if you require a visa based on your nationality. In some cases, you may be asked to provide proof of accommodation and your return trip, so it’s always advisable to have extra copies of these documents to avoid any complications. For instance, if you are staying at the best affordable hotel in Singapore, your booking documents will be valid proof that you’ll be staying at a valid address in the country.
