As it turns out, if you annoy a bank enough they’ll just sell your loan to get rid of you. After about three weeks of running the petition I received a phone call from the Office of the President at Citi Student Loans to explain how my loan was sold. As it turns out Discover bought Citi Student Loans, and Discover offers deferrals. Citi bank, at this time, does not offer deferrals for the Fulbright or Peace Corps; though they are reviewing this policy.
You can be sure I’ll be following up with Citi to see if they revise this policy.
