Passport stamps when entering US?
I'm a US citizen...I've sometimes received a stamp in my passport when re-entering the US, and sometimes not. Is there any reason they need to stamp me in? I ask because I'm getting low on pages, and I'd like to finish the next 6 weeks of travel and then renew. If I don't get any stamps upon re-entry I should be able to make it.
My theory is that they sometimes put a stamp in my passport out of habit or just consistency, but that there's no need to do so for US Citizens. If that's true then I should be ok.
