OnZoom (International Attendees)

I have an upcoming OnZoom meeting that has garnered a lot of international attention. Is there a way to allow international attendees as opposed to U.S. only? Also, will the recording be accessible to people outside of the U.S? I guess what I am wondering is if I can charge them through another platform and simply send them the recording link after the meeting or if some firewall or something will keep them from being able to review the playback if they are outside of the United States? I appreciate any insight on this!
