Citizens of many countries don't need to apply for a visa for Singapore if they intend to stay for less than 30 or 90 days, depending on their nationalities. Listed countries can be found on the Singaporean Immigration and Checkpoints Authority website. Expats from non-eligible countries will need to apply for their visa in advance, either online or at their nearest Singaporean embassy.
It's worth noting that, regardless of nationality, all expats would need an Employment Pass to work in Singapore or a Study Pass to study there. Expats will need to begin by finding employment or gaining acceptance to an educational institution to qualify.
Short-term visit pass for Singapore
Travellers allowed visa-free entry into Singapore may be allowed to enter the city-state for either 30 days or 90 days – the length of entry permitted depends on one's country of citizenship.
When arriving at the border, visitors will generally need a passport valid for six months beyond the date of entry, proof of onward/return travel and proof of sufficient funds for the duration of the visit
If needing to stay in Singapore beyond the allotted time, visitors must apply for an extension of stay. This must be done before the expiry of the original length of entry.
All other countries
Citizens not from a visa-exempt country will need to apply for a visa ahead of time. Citizens of certain countries may apply online for an e-Visa, while others will need to apply in person at their nearest Singaporean embassy or consulate.
When applying for an Entry Visa, a Letter of Introduction (LOI) from a citizen or permanent resident in Singapore will have to be submitted in addition to other documents.
Long-term visit pass for Singapore
Foreigners with a family member who is a citizen or permanent resident of Singapore may apply for a Long-Term Visit Pass (LVTP). Expat spouses who have a child in Singapore or have been living in the city-state for more than three years may be eligible for the LVTP+, which allows the holder longer periods of residency as well as other healthcare and employment benefits.
Employment pass for Singapore
If wanting to work in Singapore, it's necessary to find work so the employer can apply for an Employment Pass (EP) on the applicant's behalf. The EP is the equivalent of a work visa or work permit in other destinations.
