Okay so I'm finishing up my invites and working on the RSVP response cards.
How long should I give guests to RSVP ? "The favor of your response is requested by X"? When? Is there a rule on how long you should give guests to reply by?
Also, does the rule change for international guests? Half of my family lives in the Philippines and I am wondering if the same rule would apply?
Any advice or direction is greatly apprecieated

OH! And I should also mentioned I send Save-the-Dates to all my guests. Not sure if that changes things (?)
