Okay - So I'm trying to get the invitations squared away so that I can give the international guests at least 10 weeks. Problem is, I don't quite know how to handle the return postage. How does one anticipate the postage from India to Germany? How have others dealt with this in the past? I'm thinking to do separate RSVP cards for our guests outside the US, and indicate the rsvp on the wedding website only. Most of these guests are friends and will figure it out easily, there are just 2-4 of the groom's family who might not be tech savvy, but certainly capable at least.
