In SGP, it is nigh impossible to find pvt hospitalization insurance for foreigners with preexisting conditions. The people at International Citizens Insurance was able to direct me to a few plan options based on short email discussion with me, followed by a call with Brennan McDonnell in US who answered my questions quickly. Next step was for the underwriter to send a challenging questionnaire which requires dates and test results for ailments which they want details with. I was covered within 5 work days from applying. Their premium is similar as ACA in US with a lower deductible than in US Just to note, 5 of 5 local brokers were not successful using their SGP local underwritters.
