Canada or America?

You can't compare the cost between the two countries, the dollars are not equal to each other.

Moved to the international forum for a more appropriate response

You need to decide where you want to live, Yes retrogression is currently going to take you ryears although sitting the exam shouldn't take years but you can't just go to Canada for that reason. You need to think where you want to live in Canada, What the weather conditions are going to be like as well as lifestyle. Also CRNE exam is only sat 3 times a year in Canada but waiting times do not take as long as the US for actually getting an employer and moving to live

Silverdragon do you work as a nurse in Canada? How do you like the country overall compare to UK?

Currently I do not have a work visa as it was my husband who obtained TWP with his job. I am currently going through the process to have my paperwork assessed and hopefully sit the exam later this year
