Students studying in Foreign Schools are not eligible for grants from the US Federal government, but may apply for loans. There are three main types of loan:
In addition some private commercial lenders may be willing to offer private loans at commercial rates subject to credit rating and often requiring a co-signer.
Education Loans (Direct, PLUS and any private loans) are to cover the primary costs of education (tuition, student accommodation, books/supplies, commuter travel), and are not intended to cover other expenses, not directly related to study. You should plan a budget and make sure you have enough money for your time of study.
If you are eligible for VA educational assistance, you may also be able to use your Post-9/11 GI Bill (Chapter 33) or Survivors and Dependents Education Assistance (Chapter 35) benefits at the University of Manchester.
