My study visa was rejected stating that " We are not convinced that you will leave country at the end of your stay" and on GCMS notes its states that " Chosen Program and content at the college level at such expense appears illogical and redundant in light of PA's reported scholarly history, so program doesn't demonstrate logical progression of studies and applicant would have already received the benefits of this program. As per his previous studies and employment history, I am not satisfied with the motivation to peruse this particular program and level appears to overlap or fall below work skills already obtained by the applicant. Applicant failed to satisfy me that the selected program is reasonable given at high cost of international study as compared to local options available. So can I change my course in the same college and if yes what are the new documents that I need.
