Ah, so there IS another like myself in the same situation.
First off, I'm sorry that this situation arose and that you're in this dilemma. I am also in this pickle.
Here's what I've discovered in my dealings with 3 different colleges in 3 different states regarding transfers: It is highly ill-advised.
To be direct, you're most likely dealing with degree plan incompatibility. The further you progress in semesters, the more likely your placement will not match up or sync with a degree plan elsewhere. I won't waste time explaining this because you probably already know. Schools don't like these situations because they're complex and they don't get a whole lot of students wanting to do this sort of thing so there's no clear protocol. Nursing is now such a hot career goal that the schools are temperamental and I've been told of the need to "prove myself" as a transfer and picking up where you left off is just not an option. It doesn't make sense to me seeing that they could fill spots of students who have dropped/failed out with students who need a transfer spot that following semester.
I would second what Grntea said above and go back! If you're out of the nursing game for too long, schools are more likely to make you remediate and redo many or even all classes!
Even if you stay and work something out, you'll lose a semester or more. Calculate that in terms of money you'll be making as a nurse after you graduate. Losing 2 semesters (8 months) is 2/3 of a nurse's mean annual salary. In my state that's like $30,000.
If I leave, I will have to start over from scratch and that's IF they have a spot for me.
