The university you plan to attend or currently attend most likely will have scholarships specific to those studying foreign language education. The U.S. Department of Education has a program, The Foreign Language and Area Studies (FLAS) Fellowships, that provides money directly to higher education institutions for scholarships to students majoring in modern languages and/or international studies. Most universities that offer foreign language majors will offer scholarships for these programs. Contact your university's foreign language department as well as its financial aid office for information on every possible scholarship opportunity.
Several online databases of scholarships will let you specify exactly the major you seek. Many of these databases are free, including the most comprehensive scholarship website, FastWeb, which includes more than 1.3 million scholarships in its base. You must register before you can search, but the site allows you to save your searches, helping you to organize your scholarship quest. One drawback to searching for scholarships online lies in their availability to the entire world, rather than a specific community such as your university's campus.
Your local library will most likely have copies of reference books that list scholarship and grant opportunities from all across the nation. You can also purchase these types of books. One guide book that has a specific section about foreign language scholarships, "Peterson's Scholarships, Grants & Prizes," gives current information on privately funded scholarships from corporations and foundations. Look for books specified toward study-abroad scholarships---for example, "Financial Aid for Studying and Training Abroad" by Gail Ann Schlacter and R. David Weber. This book details up to 1,000 of the available scholarships, grants, loans, and fellowships that assist students who wish to study in a foreign country.
The U.S. government provides numerous grants and loans, such as Pell Grants and Stafford Loans, which can subsidize your foreign language teacher education and your study-abroad plans. In order to qualify for these programs, as well as all state financial aid, you must fill out the Free Application for Federal Student Aid (FAFSA). To find out about the educational financial aid programs in your state, contact your state's Department of Education.
