be realistic. if you want well-known schools with investment management master degrees, just forget about it. Schools with good brand name only offer MBA programs. Only those not so famous schools may have investment management master degrees, and many of those programs are targeting international students for money making purpose.
I've never heard about any MBA program that does not need work experiences,so,u mean there is no chance for a international student to get into a decent program without working experiences?
In fact, there are MANY MBA programs in US that do not require work experience because these schools want to MAKE MONEY. However, as you may expect, the quality of these schools/programs are pretty low. Well, even the "decent program" you refer to is MBA program, you still can not say something as absolute as "no chance". Anything is possible. Some top schools like Havard/Wharton claim that they will also accept "exceptional" undergrad straight out of schools. It is just that without work experience, your chance to getting accepted is extraordinarily slim. For non MBA masters, there are still some decent MSF/MSA programs in US that do not require work experience.
