No, I’m afraid that’s not sufficient, since Singapore has suspended all regular Short-Term visit passes, which is the usual “arrive and they let me in” process:
All Short-Term visitors are not allowed to enter Singapore, with the
exception of the following groups of travellers:
- SafeTravel and Air Travel Pass holders. For more information, visit
the SafeTravel Website. (This is for Green Lane visitors and doesn’t apply to visitors from Canada.)
- Visitors with approval letter of entry from the relevant agency in Singapore.
If you are visiting family, you will need to first to apply for a Long-Term Visit Pass (LTVP) with their sponsorship, and only after it’s been granted you can fill out that form to actually enter Singapore. Anecdotally, even if you receive the LTVP, rejection rates for entry permission remain quite high unless you have “extenuating circumstances”. Good luck and keep Travel.SE posted!
