Can nursing students apply for CNA or LPN jobs

I am a current nursing student and am finding it hard to find a job that is flexible enough for me. Can I apply to a hospital for a CNA or LPN position? If so, how far along should I be in my nursing studies?

Thanks!
Many schools will let you get your CNA license after you have completed your first semester in nursing school just by paying the fee. Check into local sitter requirements because they are a great job for students. I also always recommend waitressing or bartending because the hours are good and the money excellent.
on application put down student and when u finish, some might be interested in hiring but on a trial bases or position with no certification until you pass because alot of places need staff or do like assisted living care for over night shift that way you can study if the hours work for ya.
