If you want to work in a law firm in the future, is it better to study civil and commercial law or criminal law? What are the employment directions of economics and international economics?

Working in a law firm has little to do with what major to study. Those who study civil and commercial law can also be criminal lawyers, and those who study criminal law can also be civil and commercial lawyers. I suggest you study the major you are interested in. I prefer criminal law, but now I am a real estate lawyer.

What paralegals need is to work hard and meet the requirements of guiding lawyers. You can consider your guidance lawyer as your future client. If your service can satisfy the guidance lawyer, then you will certainly be able to meet the needs of customers in the future.

Do a good job as a paralegal, and gradually let the guiding lawyer give you more work with confidence until you can handle cases independently and become a qualified practicing lawyer.
