Best Option??

Hi everyone,

I'm currently on my gap year before starting university and for years have been debating. I have family living in California where I am without a doubt wanting to relocate to at some point in my life.
Now that it has come to the point where I need to apply for univeristy I have two options in front of me. Midwifery or Neonatal Nursing.
The thoughts that are in my head right now are which is the best option to choose. I'm aware that the US qualifications for these jobs are completely different to those in the UK and I understand that it is going to be a long process. I was just wondering which of the two jobs is the wiser choice to make taking into consideration how much easier/harder it will be to get a job in the state of California with UK qualifications and what extra qualifications I would need to gain in order to be lisenced in the US.
Are either of those qualifications enough as a whole to be considered fully trained in the US?
The neonatal course which I am looking at is a BSc (Hons) in Childrens Nursing and then Specialising in neonatal nursing once I have reached that point in my studies. Would this be enough to get a job in the US in an equivilent role?
I am seeking help before I make this decision because I am happy going on either course but I am also looking to make the best decision for my future.
I would appreciate if anyone could help, at the moment at 18 years old the whole emmigration thing confuses me ever so slightly lol, I am researching it alot and I am sure that after my university course is complete I will be 100% knowledged up on it! This is just the first step for me.
Thanks xx
