For a smooth entry into Singapore, visitors are advised to ensure that they satisfy the following basic requirements:

• A passport that is valid for at least six months
• A valid Singapore visa. To find out if you need to apply for a visa, please check with the Immigration & Checkpoints Authority of Singapore or the Singapore Overseas Mission closest to you.
• A confirmed onward or return ticket (where applicable)
• A Yellow Fever Vaccination Certificate, if applicable

For those who need an official invitation letter to support the application of visa, please submit your request to apan45sec@singaren.net.sg, with a scan copy of the first page of your passport. The invitation letter should be ready within 5-7 working days from the date of your request.
