Should I wait until we return to renew? Or would you recommend to renew before trip?
My wife and I were recently in this situation. Our passports were due to expire Nov 2026, and we have a vacation planned for April/May 2026, which would end 6.5 months before the expiration.
What tipped the scales was the post-trip vs pre-trip schedule for us. From Dec 25-Mar 26, we ONLY have US plans on the books, but post-trip, we have multiple ideas for Summer/Fall trips outside the US. IOW, if we waited until late-May to start the process (current passports are INVALID immediately when the renewal is submitted), we would be unable to forecast when we could plan a new trip in that renewal window.
So...I submitted our renewal in early Jan, and our renewals were COMPLETE and in our hands by the end of the month.
I suggest looking at your calendar of existing and possible trips and fitting the renewal into those plans. I wouldn't count on it being just a 2-3 week turn-around, but it does seem that over the past several years, folks have seen great improvements in how quickly it gets done.
