Papers from foreign authors are published all the time. The key to success for foreign authors is to make sure that their paper is written clearly in grammatically correct language. It is not enough that a paper is correct for it to be published. It has to make a significant contribution that can be understood by our readers. If an author has trouble writing a paper this way, a simple solution is often to make a small investment in hiring a text editor who can polish the author's manuscript and improve its chances of publication by making it clearer.
Papers using foreign data are welcome.
However, authors using such data should write papers that contribute to the field beyond replicating U.S. studies on a foreign dataset. It varies widely. The best way to accelerate the process is to revise a paper quickly and be responsive to advice given by the editor and the referee. Typically, an accepted paper will have undergone two or three revisions. I resubmitted my paper and received a report from a different referee.
