Mailed mine in around Dec 6 - sent extra $$ for extra pages. Got a call a few days later - no extra $$ needed for extra pages. Would I rather send a new check or use a credit card? Gave credit card on phone. Passport back within a week. Old passport arrived a few days later, with voided check enclosed.
Reused a recent passport photo - it's never going to land me a spot on Dancing With The Stars
Cheers, Anne
