Aless, I'm totally living your nightmare too. I have tried to explain to my Uni that they need to expedite the process because if they wait too long I won't be able to get my visa, which is when they told me simply going with the SAR is fine for the visa. However, I also read the post on here where someone didn't get their loans cleared, started classes and then had to scramble when the uni/dept. of ed./lender let him down.
As I said before, I am hard pressed to think of a way to make this system more inconvenient.
"effective July 1, 2006, loan money for students enrolled in foreign schools generally must be sent to the school and disbursed in multiple installments."
- this was my understanding of the process too. That the school will get three equal installments from the Dept. of Ed. for Stafford payments. Not that you need another spectre to loom over this process, but with the way the dollar is inflating, this scheme could mean more expense out of pocket for us as the dollar looses more and more against the pound and euro.
Between the new interest rate/mpn issues and the anti-terror measures (no doubt what is causing the "month" in working things out with your loans). The government is making in very hard for us to study abroad using Stafford Loans. This coupled with the UK institutions putting the general omis on the student to take care of the student loans/financing and being generally unresponsive to our needs has created a perfect storm of bureaucratic agony.
I have a job and a life I'm uprooting, the least they could do is be responsive, helpful, or even write me a letter for my visa that says "Dear whomever, The process has changed. Things are going to clear later than usual due to procedural changes but we will approve the loans so let X into the country to study at our institution. Love, X University." so that I can get my Visa and plan my life.
