回複：想在美國開個小雜貨店,需要什麽法律程序?

you should register your business with your state first. Otherwise, you will have tax problem (you need to pay business tax quarterly). If you decide to incorporate, or start as a LLC, you can do anything legal, i.e. yes, you can sell all the stuff in the same store (at least, that's the law in most states) You can try to do it on your own, but if I were you, I would hire an attorney. But if you just decide to run your business as a sole proprietorship, you can just report the tax on your personal income tax form, but you still need to register to pay state tax quarterly.
