Do I need a visa to go to Singapore with an ordinary passport? Where do I sign my name? Is it landing visa?

If you need a visa, you can apply for a Singapore visa on the website of the Singapore Embassy in China, and then submit the application to the consulate.

There is no landing visa policy to go to Singapore.

In addition, Singapore also stipulates that those who transfer to other countries or fly from other countries to Singapore for transfer must have a valid extension ticket that leaves the country within 96 hours.

If you have a valid visa/long-term visa issued by the following countries: Australia, Canada, Japan, New Zealand, Britain, the United States, Germany and Switzerland. Holders of visas from any of the above countries can stay in Singapore for 96 hours without a visa.

Extended data:

Visa is the annotation and seal of the sovereign organ of a country on the passport or other travel documents held by its own or foreign citizens to show that they are allowed to enter or leave the country or pass through it. It can also be said that it is an endorsement certificate issued to them.

To sum up, a visa is a document issued by a country's exit-entry administration department to express approval to foreign citizens.
