Baobab,
The US will give you multiple passports -you just have to give them a reason.
IE:
- The Turks won't let you in if you have a Greek Stamp (vis-a-vis).
- In the Middle East no-one will let you in, if you have been anywhere else they have fallen out with.
- Former Soviet Union: Russia; Azerbijan; Turkestan etc etc are all difficult.
But thanks for the understanding regarding doing constant travel - I did 267 nights in overseas (non-UK) hotels last year [This isn't quite true, I was "out of the UK" for 267 nights last year (according to the Inland Revenue/IRS) but this includes overnight flights].
I can tell you that that amount of travel really does hit you. Jet lag really isn't an issue, I just work on BST (UK time) wherever I am and that is that.
But when you go over the ITL and loose/gain a day that really does blow you for six (cricket metaphore).
But I am with Rudi, my biggest gripe is being messed about by immigration - wherever it is.
I am just really pleased that the US immigration service has made such improvements over the last 12 months.
