US stocks vs UK Stocks & Shares ISA after moving to the UK

I’m 19 and invested $10,000 in a US brokerage account in 2024.

I moved to the UK in 2025 and now have around £25,000 in a seperate UK Stocks & Shares ISA.

I probably won’t use my full ISA allowance this tax year.

Would it make more sense to transfer/sell the US investments and move the money into my UK ISA, or should I keep the investments in my US account? I am looking to focus on long-term growth.

Thank you!
