MS Finance for a Non-Business major(Lawyer) - Profile Evaluation

Hi everyone, 

I am a law graduate who wants to get an MS in Finance(only STEM certified - to take advantage of 3 years of post work visa). I know I am lacking fundamentals to be admitted and that is the reason I am seeking advice from you guys.

My profile:
- 24 years old from East Europe. Currently in the US on an F1 visa.
- GPA: 3.17/4.00 - The best grade was 3.23 in my year of graduation(2021). I hold the second best grade. Unfortunately the profs, unlike their colleagues from UK and US, are not flying high in East Europe. So I do not accept this GPA as a low one.
- I have done two legal internships during my studies. One of them was in the Defense Industry so I was dealing with Intellectual Property Law. Besides the legal role I had a chance to interact with clients from different countries to sell military equipment, guns and bullets. Our clients were mostly government bodies.(literally sold bullets and shields to Azerbaijan before Karabakh War)
- I have done an Erasmus Exchange in Poland and two cultural exchange to the US during summers(One of them actually taught me how to bartend).
- I also founded a trade company to trade dried and fresh fruits between Mediterranean countries and East Europe during my studies.
- I have done an internship in the field of procurement in a quick commerce startup located in San Fran, CA.
- Have been member of The European Law Students' Association.
- Have organized events under a social and political foundation that has been established to tell people about the human rights' violation happening against Uyghur minority in China.

I am curious about the admission chances. Since I am a non-business/finance major I have a plan to take online courses with credits for fundamental courses(such as Calculus, Intro to Financial Accounting and Statistics). Besides that, I would like to take the GMAT exam to demonstrate the quantitative knowledge I have(I am planing to take 3 months to prepare for it). There are different universities offering Transcripts for those fundamental courses via Outlier and Saylor etc. Would it be reputable if I took those courses online?

I am hoping to get into a school with good reputation and employment rates for international students.

Please review my profile and situation honestly. I want to know my chances and options. Any recommendation for online courses and master programs is appreciated.

Thanks in advance!!
