The study of law is a rigorous undertaking which demands a student's full attention. Therefore, the ABA Regulations (ABA Standard 304(f)) prohibit remunerative employment by full-time students in excess of 20 hours per week.
Many law schools have tighter restrictions than the ABA, prohibiting full-time first-year students from engaging in any paid employment. The faculty at many schools take this so seriously that intentional violations can be the basis for disciplinary action under the their law school Code of Student Conduct.
"But," you may say, "complying with that rule will cause a severe financial hardship."
The answer to that is that not complying with that rule will likely cause a severe academic hardship. Can one possibly juggle work and law school during that critical first year?
Probably.
Can a student do his or her "personal best" under those circumstances?
Probably not.
If it's important to you to achieve your personal best in law school, working during your first year is inadvisable. And, as pointed out above, it is violative of the ABA regulations (which apply to those law schools approved by the American Bar Association)If you have not yet begun law school and plan to work during your first year while attending full-time, you ought to reconsider.
Think it over carefully and consult with the school's Associate Dean for Student Affairs.
