Moving from UK to US

[pagan]

Considering contributing to a UK Stocks and Shares ISA before I move and before April 5th. Do you get taxed in the USA on any of the ISA, including any gains made on it?

What's the closest thing the USA has to a Stocks and Shares ISA?

What are the best options for low risk, inflation cancelling savings/investment options for lump sums in the U.S. assuming will need to access the cash in 3-5 years?

Investing in a U.S. Pension, is it easy to transfer this back to U.K. Pension if I want to come back? How about vice versa?

@pagan The ISA is taxed on the UK, also, avoid collective style fund investments as they are taxed punitively in the US under the PFIC regime.

Closest thing the US has is a ROTH IRA.

The tax treatment of the US pension when you are back in the UK is all down to the treaty.
