There is typically a week lag time for mail to get to my family in Canada. My whole Stepdads side of the family is up there so it's a significant number of people. Also, we are having a local wedding but about 75% of guests will be out of town. Should we still send all invites 6-8 weeks before? Send Canadian invites an extra week early(such as 9 weeks before)? Or just send them all a little early and request RSVP date a week earlier than normal since the Canadians sending back RSVPs will also have a delay on their end? We are sending save the dates out next month so they will have the wedding information in advance.
