HELP: Job entry in Singapore / USA / UK after MiM

I am in the 5th semester of my Bachelor's degree in Politics in Germany. After my 6th semester, I would like to take a gap year and focus on consulting internships. During my studies, I focused on cross-border M&A consulting in Asia through internships at various boutiques. I also have an internship at Deloitte.

The next step would be a Master's in Finance / Management / possibly Real Estate, as I am particularly interested in this and every recruiter would probably think im the next Larry Fink.

I want to venture into a job outside Germany. That's why I'm thinking about a Master's degree (not an MBA) in the USA, UK or Singapore. I realize that they don't really need one more business graduate and that my employer will have to sponsor a visa in all three countries.

In which country do you think I still have the best chance of finding a decent job after completing a Master's in that country?

Here are the universities I would apply to for the Master's degree.
USA: Kellogg, Booth, Ross, Fuqua (hope I spelled it right)
SGP: NUS or SMU
UK: Warwick or UCL
