will the u.s. continue to be the chief receiving nation for immigrants the world over for the foreseeable future or might someone else replace the u.s.? maybe like canada, australia, ect....? i know that historically this is how its been, but will this be the same routine for the distant future? might russia, china, brazil, ect.... actually replace the u.s. as being the chief receiving nation for people the world over? will america continue to be the chief receiving nation two centuries from now or not? what do you guys think? rsvp.
