It would be difficult to find a job. Things like babysitting and under the table work are easy to find within the expat community in Munich, but speaking English (or French, or Italian) is unfortunately not much of a marketable skill, as essentially all German citizens in Munich are comfortable using English as well, and many other immigrants speak their native language, as well as German and English. Though you can easily function without speaking German, true integration requires that you speak German.
