I am a law major, with a lawyer's license, engaged in the financial industry, and I want to get a certificate, which is more useful.
I suggest you get a qualification certificate for futures or securities, or an insurance agent qualification certificate, and then your main business is still a lawyer. It is best to mainly study cases in these fields. If you want to specialize in these fields, it is not enough to have only these basic certificates. Grass-roots employees in these financial industries are much harder than lawyers. Unless you can get the title of analyst, the title of analyst is much more difficult than the judicial examination. I wonder how many years it will take you to finish the exam. It is ok to do business in these companies, but the requirements for legal experience are relatively high, and only some big cities need it, so it is not easy to find a job.
