Lots of responses from people who aren't in the situation and can only guess. We are a 3 Kindle family of ex-pats so I know how this works. I maintain a US address and US credit card as well, but Amazon has flagged me as being in Europe, so I am not able to purchase any electronic content (ie Kindle books or .mp3 songs) from Amazon.com - I must purchase these from my home country's Amazon website. Unless you are always going to use a VPN when connecte to any type of Amazon website, and never order from your local Amazon website, this will happen. I have, however, successfully registered 3 Kindles that were all bought in the US. The only problem I had was with my Kindle Keyboard. It was given to me as a CHristmas gift. That particular model was never sold in Europe, and I had some problems with the registration process, but got through it. I tried registering it with my Amazon.com account info (and it worked), but then it blocked me from buying anything. I was able to transfer my registration to Amazon.fr eventually. Since they're now selling most of the Kindle models in Europe, I don't think this will be a problem anymore. I suspect I might have some difficulties when moving back and trying to re-establish myself as a US resident, but given what I went through to register the KK originally, I can see that it should be possible. The ion of English language books is large, without the shipping times for a lot of hard copy books, and prices are actually relatively close to what you'd pay on Amazon.com so I have no complaints in that department. Because we maintain a US address, I am able to keep my library card from that address and check out Kindle books via the Internet. No VPN needed. I LOVE being able to do this., Can I use my Kindle Fire while traveling abroad? Yes. Traveling should not impact your ability to enjoy content you have already purchased from your home country., The Apple shop has one restriction - you can only use the shop that maps to the country where your card was issued. So if you got a US issued card, then you can only buy via the US shop, but you can actually connect and download from anywhere..
