I tend to agree with the general tenor of the thread responses but without the venom
Actually I would rate UK Amex as equivalent to Australian ones (the Platinum is cheaper, for example) …. if you lived in the UK. But obviously they take a value-hit if you live outside the UK.
They can be worthwhile if you travel to the UK regularly or spend online in £. I do both. Whilst the American cards don’t have a foreign transaction fee, they have ‘fees’ in their conversion rates. Whilst they are far superior to Australian (and UK) cards in that regard, nothing beats a local currency card
I used to have a UK Platinum which I got through a Private Banking arrangement with Barclays whilst living in Australia. I closed the account during the pandemic but retained the card. Had a few issues insofar as there was something in the system that prevented getting additional cards beyond my wife.
I closed the account and now have the BA Premium card. I have hit the required spend for the companion voucher each year and find that valuable, as is the 3pts per £ on BA spend. Using vouchers next year to travel to Europe.
The process is essentially the same as the US process but in my experience the UK is much more rigorous in it’s banking, ID & address checks
As for getting Chase cards etc, it’s a great idea and I’d really like the Chase Sapphire Reserve (stillstruggle with the notion that no Australian bank offers an equivalent; something to go up against the Amex Platinum - had the Citi card but it was a bit half-coughd and I dumped it when NAB bought Citi) card but I just can’t be bothered doing the ITIN process
Good luck with the application.
