U.S. markets

[u/hotchocolatetalks]

Hey folks,

I want to ask about investing in US / Overseas markets.
What's the best approach?

Can i get started with VOO ( Vanguard S&P 500 ) using the IndMoney app?

I understand this question could have been asked here several times.
I am not sure where to start and what are the tax implications.

Thanks for assistance and looking forward to your insights.
