Singapore is pretty much the perfect choice:

1. Good CS programs: Two great universities with well-regarded CS programs - NTU and NUS
2. Language: All classes are in English; most people speak English (it's quirky Singlish, but you'll get by)
3. Infrastructure: The country and both schools have excellent infrastructure and your basic living comforts would be similar to or better than in the US
4. Travel and exposure: It's cheap and easy to explore neighboring countries (Malysia, Thailand, Indonesia, Australia, China, India, Korea, etc). You can experience a rich diversity of cultures solely through weekend getaways
5. Diversity: Singapore itself is pretty diverse - you can experience elements of Chinese, Indian and other cultures within the city-state.
6. It's not "the West": Chances are, you have visited or will visit Europe anyway. Singapore will expose you to an entirely different worldview. Yet, you will not sacrifice basic comforts that you take for granted in the US

Full disclosure - I am an NTU alumnus.

Till 2004 I worked at a multinational company with ~22,000 employees of which ~450 were IT staff. But these numbers don't tell the whole story.
The company had offices in around 130 countries, many with only a small staff. There were a few local IT personnel in most countries (included in the 450). They did on-site troubleshooting, facilities and hardware installations, etc.
Most IT staff were in 4 locations around the world, providing follow-the-sun helpdesk support. We also had operations, application development/ support, management and strategy folks at these 4 locations. The company maintained a ton of internally developed business systems, including some written in COBOL way back when.
The company was (and is) almost entirely a Microsoft/ Windows environment. In the operations team, we did everything via AD and Group Policy using terminal services/ RDP. Really, it wasn't too painful.
