I live in the UK, but have spent the last 3 months in the US with work. I have the option of moving to the US full time (which I don't want to do for a variety of mainly family reasons) but a compromise could be to spend a month in the UK, then a month in the US etc, so that I'll be splitting my time over the year between the two countries.

I'm an Amex Platinum Card holder (as well as Amex BA) and the offers on the US Platinum card would be beneficial to me during my time in the US. I've seen that there is an option to move your card from UK to US if your move is permanent, but I'm wondering if there's anything for a scenario such as mine. I'm assuming that I wouldn't be able to apply for an additional US Platinum since I don't have an official address in the US, nor will I be a US citizen? I'm not sure how it works with Amex, or credit cards in general, if I'm honest. I've read about the international dollar card, which sounds as though it's what I want, as long as this can be taken out in addition to existing UK cards.

I just tried to use the Amex chat function, but they've said I need to speak to Customer Services about it (which I'll do next week) but I wondered if anyone on here has done anything similar, or knows the guidelines?

Thanks in advance.
