UK or US for masters?

I am an RN- BSN looking to obtain my masters in midwifery. My family is planning on moving to the UK in 4 years for various reasons. I know there are short programs for adult qualified nurses to get into midwifery, some even accept international students. Those look like bachelors level courses. are there direct entry adult nurse to midwife masters programs or do all midwife masters require midwife training first? I know I won't qualify for the NHS sponsored programs.
