The problem with Imran's answer is taxation. If you are a resident of a country without a US tax treaty, you'd be paying too much in tax withholding (30%) and "you" can pay up to 55% in estate taxes after you pass.
Better options are SaxoBank and TD Direct Investing International, as your money will not be held by a US based financial institute. So, no estate taxes. Furthermore, investing in Irish-domiciled funds means utilizing Ireland's 15% taxation rate with the US and reduced rates with other countries. See US-domiciled Vanguard Total World Stock ETF (VT) vs Ireland-domiciled Vanguard FTSE All-World UCITS ETF (VWRL) comparison in the article below.

Best online stock and brokerage platform for non-U.S. residents are as follows:
1. Trade Station: Trade Station is a US stockbroker founded in 1982. It is regulated by the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA). Clients are eligible for up to $500,000 investor protection per account (including cash up to $250,000). Trade Station is considered safe because it has a long track record; discloses its financials; and its parent company, the Monex Group, is listed on the Tokyo Stock Exchange.
2. Saxo Bank: Saxo Bank, a Danish investment bank founded in 1992, provides online trading and investment services. The company is regulated by several financial authorities globally, including the Danish Financial Services Agency (FSA) and the UK Financial Conduct Authority (FCA). Saxo Bank is a global service provider, and its subsidiaries are present in the form of separate legal entities in different regions of the world. The services offered by the various entities may differ slightly, especially with respect to fees and product portfolios. In this review, we tested Saxo Bank UK. Saxo Bank is considered safe because it has a long track record, a banking background and is regulated by top-tier financial authorities.
3. Interactive Brokers: Interactive Brokers was founded in 1978 and is one of the biggest US-based discount brokers. The broker is regulated by several financial authorities globally, including top-tier ones like the UK's Financial Conduct Authority (FCA) and the US Securities and Exchange Commission (SEC). As it has licenses from multiple top-tier regulators, Interactive Brokers is considered safe. Having a long track record and publicly disclosed financials while being listed on a stock exchange are also great signs for its safety.
4. Trade Station Global: TradeStation Global is the brand of TradeStation International Ltd, which is based in the UK and is regulated by the top-tier Financial Conduct Authority (FCA).
TradeStation Global is a combined product offered by Interactive Brokers (IB) and TradeStation. Here are its most important elements:
• The account opening, deposit/withdrawal options, and available products are the same as at Interactive Brokers.
• You can use both Interactive Brokers's and TradeStation's own desktop platform.
• TradeStation Global charges its own fees, and offers its own customer support and educational tools.
Both Interactive Brokers and TradeStation are reputable brokers, regulated by top-tier financial authorities. While Interactive Brokers is listed on the NASDAQ, TradeStation itself is not: only TradeStation's parent company Monex is listed, on the Tokyo Stock Exchange.
