Well, I'll try to give you one answer~
I'm a Korean holding permanent residency, and graduated University in Korea
In Korean job market (big 4 accounting firms), USCPAs are great in demand. Why? Because many Korean companies have to file financial statements based on US GAAP, and for that, they need people who have knowledge in both Korean GAAP and US GAAP so that they can re-form the financial statement which was based in K-GAAP to US GAAP.
For financing job markets in Korea, USCPA is a plus because it is assumed that they have the ability to analyze the financial statements presented by US companies so that they can make decisions on their investment and tradings, and etc...
I guess it applies to most other parts around the world. That's probably why there are so many international students in US accounting programs.
I hope that was a good answer
