how can a US citizen buy foreign stocks?
it looks like using an ADR is the way to go here.  michelin has an ADR listed OTC as MGDDY. since it is an ADR it is technically a US company that just happens to be a shell company holding only shares of michelin. as such, there should not be any odd tax or currency implications. while it is an OTC stock, it should settle in the US just like any other US OTC. obviously, you are exposing yourself to exchange rate fluctuations, but since michelin derives much of it's income from the US, it should perform similarly to other multinational companies. notes on brokers: most US brokers should be able to sell you OTC stocks using their regular rates (e.g. etrade, tradeking). however, it looks like robinhood.com does not offer this option (yet). in particular, i confirmed directly from tradeking that the 75$ foreign settlement fee does not apply to MGDDY because it is an ADR, and not a (non-ADR) foreign security. For question #1, at least some US-based online brokers do permit direct purchases of stocks on foreign exchanges. Depending on your circumstances, this might be more cost effective than purchasing US-listed ADRs. One such broker is Interactive Brokers, which allows US citizens to directly purchase shares on many different foreign exchanges using their online platform (including in France). For France, I believe their costs are currently 0.1% of the total trade value with a 4€ minimum. I should warn you that the IB platform is not particularly user-friendly, since they market themselves to traders and the learning curve is steep (although accounts are available to individual investors). IB also won't automatically convert currencies for you, so you also need to use their foreign exchange trading interface to acquire the foreign currency used to purchase a foreign stock, which has plusses and minuses. On the plus side, their F/X spread is very competitive, but the interface is, shall we say, not very intuitive. I can't answer question #2 with specific regards to US/France. At least in the case of IB, though, I believe any dividends from a EUR-denominated stock would continue to accumulate in your account in Euros until you decide to convert them to dollars (or you could reinvest in EUR if you so choose).
Assuming you are Indian Citizen / Resident for Tax purposes. Your friend in US Citizen / Resident for tax purposes. As you are borrowing these funds and returning, this would NOT be treated as Gift but as Loan. Ensure that you have the right documentation in place. There is no tax when you receive the funds/loan or rebate when you pay back the loan. From India FEMA (Foreign Exchange Management Act) point of view, if you take loan from friends, you cannot by default repatriate funds. You have to take special permission to repatriate the funds out of India. It's important to note that the US is also the country that taxes its expats when they live abroad, and forces foreign banks to disclose assets of US citizens.  Americans are literally the property of their government. America is a tax farm and its citizens can't leave the farm. Wherever you go, you are owned.  And that now appears to be true of your Bitcoin as well. Even if you spend 50 years outside the USA, your masters want a piece of what you earn.  Land of the Free. why should I have any bias in favour of my local economy? The main reason is because your expenses are in the local currency.   If you are planning on spending most of your money on foreign travel, that's one thing.  But for most of us, the bulk of our expenses are incurred locally.  So it makes sense for us to invest in things where the investment return is local.   You might argue that you can always exchange foreign results into local currency, and that's true.  But then you have two risks.  One risk you'll have anywhere:  your investments may go down.  The other risk with a foreign investment is that the currency may lose value relative to your currency.  If that happens, even a good performing investment can go down in terms of what it can return to you.  That fund denominated in your currency is really doing these conversions behind the scenes.   Unless the bulk of your purchases are from imports and have prices that fluctuate with your currency, you will probably be better off in local investments.  As a rough rule of thumb, your country's import percentage is a good estimate of how much you should invest globally.  That looks to be about 20% for Australia.  So consider something like 50% local stocks, 20% local bonds, 15% foreign stocks, 5% foreign bonds, and 10% local cash.  That will insulate you a bit from a weak local currency while not leaving you out to dry with a strong local currency.   It's possible that your particular expenses might be more (or less) vulnerable to foreign price fluctuations than the typical.  But hopefully this gives you a starting point until you can come up with a way of estimating your personal vulnerability. Note:  This is not professional tax advice.  If you think you need professional tax advice, find a licensed professional in your local area. What are the expected earnings/year? US$100? US$1,000?  US$100,000?  I would say if this is for US$1,000 or less that registering an EIN, and consulting a CPA to file a Partnership Tax return is not going to be a profitable exercise.... all the earnings, perhaps more, will go to paying someone to do (or help do) the tax filings. The simplest taxes are for a business that you completely own.  Corporations and Partnerships involve additional forms and get more and more and complex, and even more so when it involves foreign participation.  Partnerships are often not formal partnerships but can be more easily thought of as independent businesses that each participants owns, that are simply doing some business with each other. Schedule C is the IRS form you fill out for any businesses that you own. On schedule C you would list the income from advertising.  Also on schedule C there is a place for all of the business expenses, such as ads that you buy, a server that you rent, supplies, employees, and independent contractors.  Amounts paid to an independent contractor certainly need not be based on hours, but could be a fixed fee, or based on profit earned.   Finally, if you pay anyone in the USA over a certain amount, you have to tell the IRS about that with a Form 1099 at the beginning of the next year, so they can fill out their taxes.  BUT.... according to an article in International Tax Blog you might not have to file Form 1099 with the IRS for foreign contractors if they are not US persons (not a US citizen or a resident visa holder). I don't want to get involved in trading chasing immediate profit  That is the best part. There is an answer in the other question, where a guy only invested in small amounts and had a big sum by the time he retired. There is good logic in the answer. If you put in lump sum in a single stroke you will get at a single price. But if you distribute it over a time, you will get opportunities to buy at favorable prices, because that is an inherent behavior of stocks. They inherently go up and down, don't remain stable. Stock markets are for everybody rich or poor as long as you have money, doesn't matter in millions or hundreds, to invest and you select stocks with proper research and with a long term view. Investment should always start in small amounts before you graduate to investing in bigger amounts. Gives you ample time to learn. Where do I go to do this ?  To a bank ? To the company, most probably a brokerage firm. Any place to your liking. Check how much they charge for brokerage, annual charges and what all services they provide. Compare them online on what services you require, not what they provide ? Ask friends and colleagues and get their opinions. It is better to get firsthand knowledge about the products. Can the company I'm investing to be abroad? At the moment stay away from it, unless you are sure about it because you are starting. Can try buying ADRs, like in US. This is an option in UK. But they come with inherent risk. How much do you know about the country where the company does its business ? Will I be subject to some fees I must care about after I buy a stock? Yes, capital gains tax will be levied and stamp duties and all. You can easily go to somebody like icici  ask for the demat section and enable overseas stock trading. Usually, you can buy ETFs through brokerages.  I looked at London to see if there's any familiar brokerage names, and it appears that the address below is to Fidelity Investments Worldwide and their site indicates that you can buy securities. Any brokerage, in theory, should allow you to invest in securities.  You could always call and ask if they allow you to invest in ETFs.  Some brokerages may also allow you to purchase securities in other countries; for instance, some of the firms in the U.S. allow investors to invest in the ETF HK:2801, which is not a U.S. ETF.  Many countries have ETF securities available to local and foreign investors.  This site appears to help point people to brokers in London. Also, see this answer on this site (a UK investor who's invested in the U.S. through Barclays). ML is a brokerage firm. Tell them to sell. If you can't or don't know how to do it on-line - call them and do it over the phone. Your citizenship might come in effect when tax are withheld, you need to fill form W8-BEN if you haven't done so yet. If US taxes are withheld, you can file 1040NR to request refund, or get it credited against your local tax liabilities.
