Grants are often available to provide funding for unpaid college internships. There are a variety of ways of finding the funding. One is to ask for advice in your student financial aid office. Fastweb.com recommends the book, Foundation Grants to Individuals, Phyllis Edelson (Editor) . You can often find information about funding for internships on college websites. You might check out your own college website, as well as the websites of other colleges too. To provide examples, some types of funding, listed on different college websites, will be listed here.
For some examples of the type of funding for unpaid internships which Columbia University lists on its website, lists funding for Arts and Humanities internships, American History Students, Journalism students, through the Smithsonian Institution, for minorities, for excellent students through USA Today, and many others. Dartmouth University lists funding sources as the Rockefeller Center, the Tucker Foundation, the Dickey Center, Career Center, and others.
Besides the sources listed on the college sites, you might want to be a congressional intern. If you do, have a polished resume, references, and college transcripts ready. Apply to your local congressman, or the clerk of the United States House of Representatives. Be sure you also contact your college guidance office, because you might receive credits for your internship.
