* Note that all applications for admission into our graduate programs are reviewed by a Graduate Admissions Committee and must meet the criteria indicated on this webpage. This includes applications from students who are accepted into other, unrelated graduate programs at Lehigh. Please do not apply to another, unrelated graduate program with the hope that you may be able to "transfer" into Computer Science -- it is necessary to go through the standard admission process and meet the criteria listed on this webpage.
