I have an offer from my employer to move to New York. The move is "permanent" and as such I will become a resident alien within the US. I do not wish to transfer my entire savings over to the US as I intend to return to the UK in about 2 years depending on how things go.
I am wondering how will I be taxed on interest by the IRS in the USA on my savings within the UK? The UK government will automatically deduct tax from the interest earned and so I don't want to be taxed twice.
