Question

As far as I remember, they require a license in your home country first, and be aware that is takes a couple of months or so just to find out if you have passed, and then more time to actually get a license. It is not going to be instantaneous. Those that tested in June of this year are still waiting for their licenses and they do not start the process until November.

Your visit visa or tourist visa does not permit you to work in any country as an RN, you need to go thru the immigration process for that country and meet their requirements.

There will not be one thing that you can do for there until you have passed the NLE.
