Garykung, assuming that we are talking about US passports, then perhaps you have not been to the UK in a while as US passports have been able to use E-gates for over a year, at LHR closer to 18 months in fact. Hence why I wrote what I wrote. One could be bloody minded and point out that one could request a stamp for the hell of it, or some other reason that one might have to try and get a stamp, but I stand by what I said.

Regarding China. Did I say that China stopped stamping passports? NO, I did not, different line and referring to the space saved by having long term visas for China. As I am sure you are aware that until about 5 years ago the maximum term one could get for a Chinese visa was 2 years, prior to that it was 1 year, however even those who regularly got 2 years could not get anything more than 6 months or even 2 entries back in 2007/8. So to spell it out for you, while my last passport probably had 14 Chinese visas of various flavors over a ten year period, my current passport has 3, 2x 2 years and a 10 year which will carry over after my passport expires, despite the fact that I have probably visited China far more with passport 2 than I did with passport one, hence a huge savings in pages, which was my point!
