@Sunny27 - I had a friend that recently considered a forbearance for her student loan and she told me that it was not that easy to get. She told me that for the Perkins Loan forbearance you have to meet certain qualifications before they even consider your request.
First, the loan payment must be 20% or more of your total income. They also will allow a forbearance if you develop health problems or are caring for someone that is disabled.
If you are granted forbearance you still have to pay the interest accrued during that time and the typical time frame that they will allow for this forbearance is twelve to thirty-six months.
I doubt that they will offer a forbearance because you decided to study something else. Maybe if you continue studying they will not have you begin making payments, because you are still in school but I am not sure about that.
