If you are at the beginning of this, the useful first step is not choosing a stock. It is choosing a route.
Indian investors can go global through international mutual funds bought in rupees, through directly held US stocks and ETFs under the LRS, or through GIFT City structures. These differ in what you actually own, how much control you have, what it costs, and how you are taxed — and that last one has the largest long-run effect. Picking the route first makes every later decision simpler.
After that, the sequence is fairly mechanical: complete KYC, remit funds under the LRS, file Form W-8BEN so US dividend withholding drops from 30% to the 25% treaty rate, and place your first trade. The articles below cover both halves — the strategic choice of route and the practical steps once you have chosen.
