Do Thailand passport holders need a visa to visit Singapore?

Visa-free up to 30 days under ASEAN reciprocity. SGAC mandatory before arrival. Thai ordinary passport holders enter Singapore visa-free for up to 30 days per entry under the ASEAN reciprocal visa exemption agreement. The exemption covers tourism, business meetings, family visits, and transit. All travellers must submit the free Singapore Arrival Card (SGAC) electronically within 3 days before arrival, including health declaration. Singapore's automated clearance system at Changi Airport accepts Thai biometric passports for fast-track entry after first manual enrolment. Thailand-Singapore travel is dominated by leisure trips (Sentosa, Universal Studios, Gardens by the Bay) and business connections to Singapore as a regional finance hub. Officers may sometimes issue 14-day passes for first-time visitors. For work, study, journalism, or stays beyond 30 days the corresponding Singapore pass is required (Employment Pass, Student Pass, etc.) — Singapore does not generally extend visit passes in-country.
