I have been affiliated with several colleges in and around Baltimore. I don’t know of any college where the advisors can alter your grades or GPAs. I do know that he advisors are very important to international students. They should be knowledgeable of visa regulations and requirements. Also they should be able to give you advice on what classes you should take and in what order. Unfortunately many people have a hard time taking responsibility for themselves. You may have spoken to people who did poorly in a class or program then blamed the advisor for their academic status. If you have an advisor that you feel is giving you bad advice I would suggest talking to them first. Make an appointment and explain exactly what you need and your concerns. It may just be a case of communication. If after this meeting you feel that your needs are still not being met meet the director of counseling to discuss your concerns. Also I would highly recommend that you be proactive in your education. Find out what resources are available to you (tutoring, writing center etc) take advantage of these to help keep your grades high. Second, be sure you understand what is necessary to maintain your student visa. Contact immigration and/or your embassy for help with this. If you maintain adequate grades and immigration status there is nothing your advisor can do to hurt you. Good luck.
