OMGoodness Hon, it's great to have ambitions, but it doesn't seem as though you have a clear understanding of nursing practice yet. There is no 'specialization' to choose in your pre-licensure education. You will graduate as a generalist. There is no "choose" specialty option at all. Specialization only comes with graduate education.
When you graduate & pass your NCLEX, you are probably going to have to really scramble just to find a job -of any kind - since the job outlook for new grads is very dismal, and will most likely remain that way.
Another point of clarity. Travel & correctional are not 'specialties' per se... just settings in which patient care occurs. Rural nursing could be considered a specialty only in some instances... most rural hospitals have the same patient care divisions as the bigger ones. Emergency & Psychiatric are nursing specialties but not infectious disease - that's a medical specialty since nurses care for patients with infectious diseases in many different settings. Likewise Forensic nursing - that requires specialty education and certification... and can take place in any setting in which that type of patient is cared for.
For now, it would probably be best just to focus on getting the most out of your nursing education, maxxing out your GPA and preparing for the almighty NCLEX. If you get a chance to choose clinical experiences, you can try to focus on one of your areas of interest.
