So it is your big big wedding, and who you want to be invited? Your parents, your BFF, and you want someone bigger and more famous?
How about the United States President Obama and his wife?
Someone did it, and they send their invitation to President Obama at the White House. here is what they got back

As a fellow Canucks, of course we don’t invite the President of another country. We invite our Prime Minister of Canada Stephen Harper.
I highly recommend you to give it a try, and let me know how it turns out!
