I would like to know are there are any scholarships for taking finance courses in the USA?
How do I find a scholarship in Finance in the USA? - Forum
I think I found one scholarship that might be of interest to you. It's called the Hubert Humphrey Fellowship and it's offered through the US State Department's Fulbright Program.
It's especially for professionals who would like to study in the U.S. for just a year and finance is one of the areas of study you can choose.
Contact your local U.S. embassy and ask about it!
