Connecting through another country?
This page covers a direct flight to Singapore. If your route connects through a third country, that country may require its own transit visa — sometimes even for a short stop inside the airport between flights (a layover). Transit rules depend on your specific routing, so check the country you connect through separately, or analyse your full itinerary.

Check your phone coverage abroad
INFOYou're travelling to Singapore (SG). Your home cellular plan may or may not include data abroad — check your carrier's international options before you fly. An eSIM is a low-commitment alternative if your plan doesn't cover the destination or charges high roaming rates.
Singapore (SG) checks criminal history on entry to
INFOSingapore (SG) screens applicants and arriving travellers against criminal records (immigration screening). If your history is clean, no action — proceed normally. If you've ever been convicted of anything, two things matter: (1) any visa or entry-permit application asks the question, and answering 'no' when the answer is 'yes' is itself grounds for refusal even if the original conviction wouldn't have been; (2) some categories trigger denial regardless — the canonical examples are DUI for Canada and drug-related convictions for Japan. Research waivers / rehabilitation routes well before booking if either applies to you.

Fill out Singapore Arrival Card before you fly

Check your medications against Singapore (SG)'s import list
INFOSingapore (SG) restricts or bans the import of: codeine, morphine, cannabis-derived products (including CBD), benzodiazepines. The risk is real — travellers have been detained at customs for over-the-counter products that are routine elsewhere. If you take any prescription medication, look up the active ingredient against the restricted list above before booking. Always carry the prescription bottle plus a doctor's letter naming the medication and the condition it treats. Adding your medications to your profile (optional) lets us tell you specifically which of yours match. Singapore has severe penalties for controlled substances. HSA approval needed for many medications.
