@Carolyn ********
i dont think it relevant but i came into sandbox middle of september. I have a Non O visa which expires october 24th so just 5 week so i purchased 2 month insurance.
Singapore embassy were insisting that non O have 1 years worth of covid insurance.
So we had two day of e mails going back and for, i changed COE to visa exempt then they told me ok please change back to non O. Blah blah
