Dear Mr. John,

I am writing to express my interest in attending the upcoming business seminar in the US. I understand that the seminar will cover xyz, and I believe it would be an excellent opportunity for me to expand my knowledge and expertise in this area.

Please provide me with additional information regarding the seminar. First, could you please provide me with the seminar's exact start and end dates, as well as its duration? This will enable me to plan my travel and ensure that I have no conflicts attending the seminar.

In addition, could you please inform me about the accommodations that will be provided during the seminar? Will it be possible to stay in a hotel close to the seminar location, or will I need to make separate lodging arrangements?

Lastly, could you provide me with information regarding the cost of attending the seminar, including any registration fees, travel expenses, and lodging expenses? This will help me determine whether I can afford to attend the seminar.

Thank you for taking my inquiry into account. I anticipate hearing from you in the near future and hope to be able to attend the seminar.

Sincerely,

ABC
