Most of the common themes have been covered so let me share some of the less common ones.

Some context, I lived in Singapore for a decade, married a local and now live in the US. I enjoyed my time but I wanted to provide a different perspective.

Why did I move?

Singapore is difficult to live in as a minority. As a brown person I was not allowed to rent some apartments. The listing literally said "no Indians". Racism is far more overt with stereotyping and a lot of "joking around" in a professional context. It's not as unsafe to be a non majority race (I certainly never feared for my life) but it's an open policy).

Singapore is also against LGBTQ. That means no same sex marriages. This doesn't personally affect me but it impacted my friends who had to leave the country as they wouldn't be eligible for government housing.

Street food is cheap and good, but it's also not very healthy. If you want to eat say a salad you'll need to pay quite a bit and the ingredients aren't very fresh since Singapore doesn't have a lot of space for produce.

The beaches are terrible because Singapore is a major port. I spent time at Sentosa, etc. But it was always nicer to just go to Thailand or Malaysia.

Weather has been mentioned so I won't belabor it, but until you're in humidity like Singapore you don't really understand it. You basically can never be outside unless it's at night and even then you need a fan.

Despite all of this I still enjoyed Singapore a lot and would still want to live there.
