I agree with the above poster, you need to contact schools of interest first! In addition to the troubles you may encounter mentioned above, there is another issue to consider. From what I have gathered after reading many posts, not all nursing schools are alike!
For example, some nursing schools cover Psych the first semester while others cover it the third semester! Med Surge may be covered the second semester while some other schools break it up between two semesters! Not to mention some schools do not begin clinicals until second semester or the end of first semester compared to those that begin clinicals during the first few weeks of first semester.
Therefore, being a second year student at your school may not mean SQUAT at other schools since you may not have covered the material and/or may not have as many clinical hours as is expected of a second year student. If any of this is the case, you will end up having to start all over!
If you have to start over that is a complete waste of your time and money. Especially since some schools will not accept your pre-requisites for various reasons. I highly suggest you stay where you are at
if you cannot make a smooth transition into another nursing school.
However, if you have no choice but to move, then consider becoming a LPN (if it is allowed) before you move. As a LPN your worse case scenario may involve a few pre-reqs and possibly a course that bridges you into a regular RN program in another state. This might be an extra semester or an extra year, but at least you may not have to begin from scratch. Good luck.
