我最终的目标还是要回国的。现在有长江了，把西方的经验和中国环境结合后传授给学生。那么北美的mba还有什么优势呢？

an international MBA means a cross-culture background, an international network, and job opportunity in a foreign country.

that is not available in any domestic MBA.

Exotic life experience is a treasure.

 well, a top20 MBA in US does make difference. remember that many companies only recruite certain ranked schools. (that does not necessary mean the opportunity is avaliable to everyone in top 20 programs)

otherwise, a chinese MBA is just as good as a US MBA

长江也好,中欧也好,目前都还算不上是国际化的商学院.仅凭这点, 就无法和美国的比.

如果读MBA的目的只是回来找份好点的工作,那么为什么不考虑其它中国大学的MBA呢?它们可是很本土的啊,并且国内的网络还很强

 according to your situation, if u can't enter top 20, you should chooe the best in China.

如果你打算在中国公司工作，那国内的MBA可能（也只是可能）更适合你。不过我好奇的是，国内MBA研究的案例都是中国公司的吗？如果也是照抄国外的案例，那么就区别不大了

至于Top20的MBA是否很难，这取决于你自己的很多方面了，如工作经历，GMAT和TOEFL，Essay，推荐信和面试等。
