At first, I am available to be at the Research Center five days a week. As the original language course that I have signed up is having the Spring Break right now, I have enrolled another language course recently, which will have classes every Tuesday and Wednesday.
I am writing this letter to request for a leave of absence from the Research Center so that I can attend my language course.
Thank you for your understanding and support you have given me in the past. I hope you will give this request serious consideration.
