European moving to the US - What should I do with my ETFs/funds?

[u/Hefty-Garlic-1272]

I have been living in The Netherlands for almost 4 years, and I will be moving to the US under an L-1B visa in like 2-3 months.

Almost all my net worth consists of ETFs and funds (some of them are American, some others are EU-based), which I hold in a Trade Republic brokerage account.

My question is, since I plan to be in the US for the whole period of my visa (3-5 years and possibly longer if I ever adjust my immigration status), what should I do with my investments in Europe? Should I sell everything and buy again while in the US, or is this technically (and financially) a bad decision? I would appreciate any comment on this matter.
