Help with endorsement of license

I'm Canadian and will be writing my NCLEX next week. I want to work in NC. I received my ATT through Minnesota. I've just started applying for work and found out today that Minnesota is not a compact state. I was advised by the NC nursing board to go ahead with the NCLEX and license through Minnesota and then apply for endorsement. I've done a partial application on their website. Does anyone know what will be involved in this process and how long it will take? Will I need to now go through another credentialling process? I have an employer that will give me an offer letter for the TN visa but not until I get my NC license. I have been on a 3 month leave of absence from my job in Canada and need to go back soon, I'm trying to get as much done as I can while I'm here in NC. Thanks for your help.
