Contact the local hospitals and facilities in your area to see what is offered. You also should check out tuition and fees at various Colleges and Universities.
To answer your question, although you may only be eligible for one thing, yes many places still give sign on bonuses and have loan forgiveness plans. However, you may become angry later if you sign up for them because the pay back is usually nothing compared to the amount of debt students rack up attending schools.
Usually students attend expensive schools and/or take out loans to cover cost of living. Plus, a big sign on bonus is usually an indication that the facility has a high turnover rate for a reason such as poor working conditions. Never mind the fact that the sign on bonuses are not enough to cover the amount of debt students take out either.
If you can pay as you go, that is your best bet. Then you can receive a sign on bonus and it really will feel like a bonus. As a RN you can also sign up to have future tuition and fees paid while you further your education part-time as you work full-time in many places.
I am working on my ADN and already have an MBA. I am paying cash. I will apply for several scholarship for both my ADN and my BSN but if I receive nothing, I am still able to make my tuition payments and cover costs. I have saved up over the years and I continue to work part-time until I receive my license, then I will work full-time again. Good luck!
