How to start investing for an immigrant?
For starting with zero knowledge you certainly did a great job on research as you hit on most of the important points with your question.  It seems like you have already saved up around six months of expenses in savings so it is a great time to look into investing. The hardest part of your question is actually one of the most important details.  Investing in a way that minimizes your taxes is generally more important, in the end, than what assets you actually invest in (as long as you invest even semi-reasonably).  The problem is that the interaction between your home country's tax system and the U.S. tax system can be complex.  It's probably (likely?) still worth maxing out your 401(k) (IRA, SEP, 529 accounts if you qualify) to avoid taxes, but like this question from an Indian investor it may be worth seeing an investment professional about this.  If you do, see a fee-based professional preferably one familiar with your country.   If tax-advantaged accounts are not a good deal for you or if you max them out, a discount broker is probably a good second option for someone willing to do a bit of research like you. With this money investing in broadly-diversified, low fee, index mutual funds or exchange traded funds is generally recommended.  Among other benefits, diversified funds make sure that if any particular company fails you don't feel too much pain.  The advantages of low fees are fairly obvious and one very good reason why so many people recommend Vanguard on this site.  A common mix for someone your age is mostly stocks (local and international) and some bonds.  Though with how you talk about risk you may prefer more bonds. Some people recommend spicing this up a bit with a small amount of real estate (REITs), sometimes even other assets.  The right portfolio of the above can change a lot given the person.  The above mentioned adviser and/or more research can help here. If, in the future, you start to believe you will go back to your home country soon that may throw much of this advice out the window and you should definitely reevaluate then.  Also, if you are interested in the math/stats behind the above advice "A Random Walk Down Wall Street" is a light read and a good place to start.  Investing makes for a very interesting and reasonably profitable math/stats problem.
