Dear Mr. Zhang,
Thank you for accepting the invitation to visit the Department of Computer Science at the University of Lalaland. We are glad to welcome you. During your stay, your activities will include participating in a series of lectures on computer networking, attending the conference on cloud computing, giving a lecture on the impact of broadband Internet services in rural India, and attending a workshop for team building and management.
In order to enter the U.S., you will need to apply for a Business (B-1) visa at the U.S. Embassy/Consulate that has the jurisdiction over your place of residence. As it may take a long time to get the visa interview appointment and actually get the visa, we suggest that you plan well in advance.
If you have any questions or concerns regarding your upcoming visit, please feel free to contact Ms. Jennifer Douglas at [email protected] or by phone at (972) 555-1212.
Sincerely,
/Signature here/
Benjamin Fox
