I thought I would use this thread for a general question...

I am down to 2 pages left for visa stamps. I move around a pretty decent amount, and I am at the point of trying to get immigration officers to stamp in "efficient" locations to maximize spaces on the pages ... but you know how that can go sometimes.

I will be back in the USA for 4 weeks over the holidays but I would love to squeeze a bit more out of my passport book versus sending it in to get a new one if I can help it. It doesn't expire until 2020 so time wise I have plenty of time.

My question is ... has anyone had luck traveling internationally and getting immigration officers at countries to stamp in random, tight spots on pages until the passport is literally so jam packed it would HAVE to be renewed?

This is my first passport I am maxing out so maybe I am naive and what I describe above is part and parcel for grizzled travelers, but I am asking because I'd love to not have to deal with renewing it quite yet and just keep finding open space on random pages assuming this isn't some sort of taboo thing for some weird reason?

EDIT - part of why I ask is because I occasionally hear the typical fine print line of "must have at least 2 open visa pages" for acceptance into a country, blah blah. I have no clue if that is just a line they say but do not really enforce, or if it actually is a big deal. It's part of why I am trying to keep my last 2 blank pages open.

I of course have 2-3 pages open additionally of endorsement pages, but as far as I know those aren't supposed to be used for visa stamps. However, I am sure if it's all you have, then it will get stamped right? Versus denying you?
