When you visit with your birth certificate, you will need to be prepared to encounter lower level employees who may not be helpful.
Their knowledge of how to handle exceptions like your situation may be limited. Remain calm, and ask to speak with their supervisor. If the supervisor is not helpful, ask who that person’s boss is.
If someone tells you their office is not able to help you, ask them to direct you to someone who can assist you.
You may have to try several different approaches if you don’t have success walking in and asking for help from administration. Talk to your academic advisor, or a professor in your major.
Look online and find a contact name of a really high up leader. Dean of Students may be a good person to speak with if there is such a position at your college.
Before you attempt this in person, write a short, two paragraph summary of who you are, your student ID number, and the basic facts. Do not be negative or angry in your letter or in person. You are simply stating facts, pointing out their error, and asking for their error to be corrected. Be sure your contact name, email address, and phone number are listed on the letter in bold type.
Make several copies of your letter, since you may have to visit multiple offices before you connect with a person who is willing to listen and assist you. You may encounter folks who say their boss is not in, and you will want to write down name, email address and phone number for each supervisor type person you leave a letter for.
Plan to follow up with emails to each supervisor you speak with or leave a letter for. I would follow up within 24 hours of initial contact.
Do not give your original birth certificate with them, but you may have to give them a copy. Again, make several copies before you arrive. Bring your drivers license as additional proof, along with any official mail you receive that has your name listed correctly.
Another possible ally is someone from your high school, a guidance counselor or trusted teacher. Just tell them your story and ask for their help.
I am sorry you have to deal with this. My husband had an older relative with your name, and I spent years misspelling it.
