What are the differences of Near in the manga version?

Do manga publishers only accept the original work of Japanese artists and storywriters?

• The gist of what I'm asking is... would it be possible for a group of Americans, who have no Japanese relations, to have their manga published by a popular company (like Shonen Jump, for example) if there's enough genuine quality to it? Or is it strictly a Japanese thing? Sure, there would probably be a few differences... like the English version being the original instead of a Dub/Sub, and perhaps a few changes in the art style. If anyone could give me a straight and honest answer here (and preferrably provide proof of your point), I'd much appreciate it! :)

• Answer:

  I can't say for sure that they'll deny it, but tbh I'm pretty sure it'll be hard to even submit your manuscript in the first place, having no connections and not being able to speak the language. Japanese mangaka have enough trouble getting their work published, a bunch of Americans practically have zero chance. If you're dead set on publishing a manga/comic, why not just turn to American publishers? Or even better, publish it as a webcomic, which doesn't even cost any money or trouble. If the manga is of good quality, it'll become popular enough, and publishers will want to take you on. There are several animes that started out from webcomics, and became popular to be published in print and be made into anime.
