Yes. Absolutely, in general, you can work a job or related field while attending college. In fact, many career counselors recommend that you do so your practical experience can compliment your coursework and vice versa. Whether you can attend college full-time or part-time, and whether your employer has any rules or limitations on your ability to work and attend college simultaneously are things you will need to discuss with your employer and with the college, because they vary from employer to employer and college to college. Some employers may have special prohibitions, requirements to obtain authorization before attending school, or ethics rules that may apply, etc. Also, some employers may provide funding or stipends toward college, so that is also worth checking into. Best of luck.
