在Kellogg的application instruction里看到有关国际学生贷款部分的介绍如下：
Loan programs available to Kellogg full-time MBA/MMM International
Students include the Northwestern University International
Loan Program, which provides two distinct options: the student
either includes a U.S. Citizen or Permanent Resident Cosigner for
Option A, or an International Cosigner for Option B. Other Private
Loans are available to International Students, but the lender may
require a U.S. Citizen or Permanent Resident Cosigner.
里面的意思是 1.要么找个美国公民或绿卡持有人作cosigner申请Option A. 2.要么找个international cosigner申请Option B. 3. 要么申请private loans，但是也可能要求有个美国公民或绿卡持有人作cosigner。
