Moving to USA from UK, best option for PSN account?

Hi guys,

I'm moving to the US in a few weeks and will be selling my current PS4. Going to pick up a new PS4 Pro when I arrive in the US.

Will I be able to keep using my UK account? I'm only going to be there for a year, so having to make an entirely new account and lose all my saves, trophies and friends seems like a hassle. I figure I can just use PayPal as the payment method and it'll be fine right?

I've uploaded all my saves to the playstation cloud, so I'm I can just reinstall and download those saves again?

Also, will my UK disc games work on the US PS4 Pro? I was planning on keeping them rather than having to buy them all again.
