How to open a Mega Money Market account without an ssn?
According to the IRS:  Aliens who are not eligible to apply for a U.S. social security   number, or who do not meet the Social Security Administration's   evidence requirements for an SSN, may apply for an Individual Taxpayer   Identification Numbers (ITIN) from the Internal Revenue Service if   they have a valid tax reason for needing an ITIN, as explained in the   Form W-7 instructions. Seeing as you don't have a valid tax reason for an ITIN, your request will probably be denied by the IRS.
TL; DR version of my answer: In view of your age and the fact that you have just opened a Roth IRA account with Vanguard, choose the Reinvest Dividend and Capital Gains distributions option. If Vanguard is offering an option of having earnings put into a money market settlement account, it might be that you have opened your Roth IRA account with Vanguard's brokerage firm. Are you doing things like investing your Roth money into CDs or bonds (including zero-coupon or STRIP bonds) or individual stocks? If so, then the money market settlement account (might be VMMXX, the Vanguard Prime Money Market Fund) within the Roth IRA account is where all the money earned as interest on the CDs or bonds, dividends from the stocks, and the proceeds (including any resulting capital gains) from the sales of any of these will go. You can then decide where to invest that money (all within the Roth IRA). Leaving the money in the settlement account for a long time is not a good idea even if you are just accumulating the money so as to be able to buy 100 shares of APPL or GOOG at some time in the future. Put it into a CD in your Roth IRA brokerage account while you wait. If your Roth IRA is invested only in Vanguard's mutual funds and is likely to remain so in the foreseeable future, then you don't really need an account with their brokerage. You can still use a money market settlement fund to transfer money between various mutual fund investments within the Roth IRA account, but it really is adding an extra layer of money movement where it is not really necessary. You can sell one Vanguard mutual fund and invest the proceeds into another Vanguard mutual fund or even into several Vanguard funds without needing to have the funds transit through a money market account.  Vanguard calls such a transaction an Exchange on their site. And, of course, you can just choose to reinvest all the dividends and capital gains distributions made by a mutual fund into the fund itself. Mutual funds allow purchases of fractional shares (down to three or even four decimal places) instead of insisting on integer numbers of shares let alone round lots of 100 shares. All this, of course, within the Roth IRA. "I'm adding to @Dilip's basic answer, to cover the additional points in your question.  I'll assume you are referring to publicly traded stock options, such as those found on the CBOE, and not an option contract entered into privately between two specific counterparties (e.g. as in an employer stock option plan). Since you are not obligated to exercise a call option you purchased on the market, you don't need to maintain funds on account for possible exercising.  You could instead let the option expire, or resell the option, neither of which requires funds available for purchase of the underlying shares. However, should you actually choose to exercise the call option (and usually this is done close to expiration, if at all), you will be required to fund your account much like if you bought the underlying shares in the first place.  Call your broker to determine the exact rules and timing for when they need the money for a call-option exercise. And to expand on the idea of ""cancelling"" an option you purchased: No, you cannot ""cancel"" an option contract, per se.  But, you are permitted to sell the call option to somebody else willing to buy, via the market.  When you sell your call option, you'll either make or lose money on the sale – depending on the price of the underlying shares at the time (are they in- or out- of the money?), volatility in the market, and remaining time value.  Once you sell, you're back to ""no position"".  That's not the same as ""cancelled"", but you are out of the trade, whether at profit or loss. Furthermore, the option writer (i.e. the seller who ""sold to open"" a position, in writing the call in the first place) is also not permitted to cancel the option he wrote.  However, the option writer is permitted to close out the original short position by simply buying back a matching call option on the market.  Again, this would occur at either profit or loss based on market prices at the time.  This second kind of buy order – i.e. made by someone who initially wrote a call option – is called a ""buy to close"", meaning the purchase of an offsetting position.  (The other kind of buy is the ""buy to open"".) Then, consider: Since an option buyer is free to re-sell the option purchased, and since an option writer (who ""sold to open"" the new contract) is also free to buy back an offsetting option, a process known as clearing is required to match remaining buyers exercising the call options held with the remaining option writers having open short positions for the contract.  For CBOE options, this clearing is performed by the Options Clearing Corporation.  Here's how it works (see here): What is the OCC? The Options Clearing Corporation is the sole issuer of all securities   options listed at the CBOE, four other U.S. stock exchanges and the   National Association of Securities Dealers, Inc. (NASD), and is the   entity through which all CBOE option transactions are ultimately   cleared. As the issuer of all options, OCC essentially takes the   opposite side of every option traded. Because OCC basically becomes   the buyer for every seller and the seller for every buyer, it allows   options traders to buy and sell in a secondary market without having   to find the original opposite party.   [...]   [emphasis above is mine] When a call option writer must deliver shares to a call option buyer exercising a call, it's called assignment.  (I have been assigned before, and it isn't pleasant to see a position called away that otherwise would have been very profitable if the call weren't written in the first place!) Also, re: ""I know my counter party cannot sell his shares"" ... that's not strictly true.  You are thinking of a covered call.  But, an option writer doesn't necessarily need to own the underlying shares.  Look up Naked call (Wikipedia).  Naked calls aren't frequently undertaken because a naked call ""is one of the riskiest options strategies because it carries unlimited risk"".  The average individual trader isn't usually permitted by their broker to enter such an order, but there are market participants who can do such a trade. Finally, you can learn more about options at The Options Industry Council (OIC)." how do they turn shares into cash that they can then use to grow their business? Once a Company issues an IPO or Follow-On Public Offer, the company gets the Money. Going over the list of question tagged IPO would help you with basics. Specifically the below questions; How does a company get money by going public in an IPO? Why would a company care about the price of its own shares in the stock market? Why would a stock opening price differ from the offering price?  From what I've read so far, it seems that pre-IPO an investment bank essentially buys the companies public shares, and that bank then sells them on the open market. Is the investment bank buying 100% of the newly issued public shares? And then depositing the cash equivalent into the companies bank account? Additionally, as the stock price rises and falls over the lifetime of the company how does that actually impact the companies bank balance? Quite a bit on above is incorrect. Please read the answers to the question tagged IPO. Once an IPO is over, the company does not gain anything directly from the change in shareprice. There is indirect gain / loss. Congratulations on the new arrival! Technically, a gift by check to the baby should be deposited into a newly established custodial account in the baby's name. To open one, you will need to have a SSN for the baby, so don't wait till tax time to request one (you will need the SSN if you wish to claim the baby as a dependent on your 2017 income tax returns). On the other hand, people are often cavalier about this and at least one bank (JoeTaxpayer's!) seems not to care about the legal niceties; I expect my bank wouldn't have either, in the good old days. Note that @JoeTaxpayer and I are of similar age, and perhaps he too is recounting experiences from some time ago. It is possible, i've contacted different banks, and only one bank (Wells Fargo) didn't say that they need all members in person, but gave me a form which my colleague filled to authorize me to open an account. Wells Fargo.  They have an account called PMA, an umbrella account for checking, savings, mortgage, and brokerage accounts.  It would cost $30/month, but I never had to pay because I have a rollover retirement account that is enough to waive the fees.  They count all accounts, including mortgage, which I used to have.  Oh, and no restrictions.  An added advantage is there are no fees for any of the accounts, nor for some other things, like bank checks, outside ATM fees, etc.    I'm in California, so I don't know if the same deal exists in other states.  But if you qualify for the free account, it's pretty good.  Actually, most of my investments are Vanguard funds.  And I have another rollover account with Vanguard, and never pay fees, but I only buy or sell from one Vanguard fund to another, and rarely since I have targeted retirement funds that are designed to be no maintenance.  For some reason, I trust Vanguard more than most other funds; maybe because I like their philosophy on low-cost funds, which they started but are now getting more popular. You setup a self-directed solo 401k by paying a one time fee for a company to setup a trust, name you the sole trustee, and file it with the IRS. None of these companies offer TPA because it opens them up to profit leaching liability. After you have your trust setup, you can open a brokerage account or several with any of the big names you want (Vanguard, Fidelity, Ameritrade, etc), or just use the money to flip houses, do P2P lending, whatever, the world is your investment oyster. If the company has recurring fees you need to ask what is going on because if they aren't offering TPA services, then what the heck could they be charging you for? I did see one company, I think it was IRA Financial Group, that had the option of having a CPA do TPA for you for a recurring fee, but I would pass on that. The IRS administration requirements are typically just the 5500-EZ that you have to file as a hard copy by July 31 if your investments are worth more than $250k, on December 31. Yes, you have to get the actual form from the IRS, write on it with a pen and mail it to them every year, barbaric. You can either have your accountant do it or do it yourself. If you're below $250k just google solo 401k rule change two or three times a year and don't try to launder money. If anything, the rules will loosen with time, I don't imagine the Republican Congress cracking down on small business owners any time soon. The easiest options appear to be to open an account with one of the large multinational banks like Citi. They have options such as opening two separate checking accounts, one in each currency, and Citi in particular has an international account that appears to make mutli-currency personal banking easier. All of the options have minimum balance requirements or fees for conversion, but if you need quick access this seems to be the best bet. Even if this is a one-time event and you don't need the account, a bank like Citi may be able to help you cash the check and get access to the funds quicker than a national or local bank. http://www.citibank.com/ipb-global/homepage/newsite/content/english/multi_cap_bank_depo.htm Alternatively if you know anyone with a US bank account you can deposit it with them and take the cash withdrawal from their account, assuming they agree, the check isn't too large, etc.
