My parents are here with me for the time being. They would like to visit you and have a short meeting with you. Will you be available in the following days (someday this week)? If so, could you please let me know when it is convenient to you?

这是要求老师提时间的，也可说。

My parents are here with me for the time being. They would like to visit you and have a short talk with you. Will you be available in the following days (someday this week)? Is it OK for this Thursday afternoon? If you will be busy then, could you please let me know when it is convenient to you?

这是你自己先提出一个时间的。
