and I see the issue --- where as Dept of education suggests and IRS requires EIN for the foreign institution , there appears no easy way to find the data. However, under the rules the institutions are required. cajoled to send form 1098_T to you. Only then you can fill out the required information -- supposedly they do get EIN issued by the IRS for this purposes.
