Would there be any problem if I have done my economics masters again?

It is generally acceptable to pursue a second Master's in Economics in the U.S., especially if you can clearly explain how it fits your career goals or offers needed specialization. Admissions committees expect a strong reason for repeating the degree, so be sure to highlight your motivation in your statement of purpose.

If your application does not show clear progression or purpose, it may raise concerns about your academic direction. Strengthen your profile with a solid quantitative background and relevant coursework. Some programs may also require GRE scores.
