There is some confusion and want to clear it up.
For URL structure, do you recommend [domain].com/[country]/[state]? Is there a better format to use? For example, [domain].com/[2 letter language code]-[2 letter country code]/[state]
For the above State page, what should I put re: "href...." if any?
Where do I insert rel canonical? On every page, including the homepage? ONLY on duplicate pages?
If I have a non-English page, is there an advantage of having the meta data in that language vs. English?
