I am scheduled to visit the US on business at the end of this month, and wish to call on you at your office on that occasion.
I will be arriving in Washington on or around August 20 and staying there for about a week. It would be very much appreciated if you would kindly arrange to meet with me either on August 22 or 23, whichever is convenient for you. If neither is convenient, could you please suggest an alternative date by return e-mail.
Thank you in advance for your kind cooperation. I am looking forward to meeting you in Washington soon!
