Name Change

<p>I hope this is where I'm supposed to post...
Oh well hi! I will be a college freshman next year and was wondering when I should change my name.
I was born with an ethnic name and when I moved to the U.S, my parents decided I should use the name "Kimberly" because my legal name is too hard to pronounce. I consider Kimberly as my name (since no one even calls me by my legal name) and would like to change it as soon as it would be convenient. I had originally decided to change it after getting into my first year (so I wouldn't have issues in the college application process) but now my parents believe otherwise because they are afraid it would "complicate everything." I feel like I have waited long enough and it would just be wrong to wait until after college. I plan to change my name to Kimberly then have my legal name be my middle name. When would be the best time to try and do this? (I turn 18 soon)</p>
