Below is my letter to ask about "Homestay in a New Zealand Family"


Homestay in a New Zealand family
You are going to visit New Zealand for an 'English and Homestay' program. You have just received details of your homestay host family.
Write your first letter to the family. In your letter

• introduce yourself
• ask the family some questions to get information that is important to you
• tell the family about your arrival date and time.

Dear Mr. Joshua

I am writing to inquire about the “English and home stay program”. First of all, I would like to introduce about myself generally. My name is Ms.Maw, I come from Thainland. I will have a homestay program for three months in new Zealand. I saw the advertisement of your homestay host family. I would like to get the detail information about it. Firstly, I need to know about the cost for three months home stay at your house. What is included on that cost?. Secondly, I would like to check whether the location of your house is close to train station. I am looking the house that is close to the train station because it will be easier for me to go to the city. Thirdly, what are the restriction and the rule during the home stay program at your house? Finally, regardless the payment method shall I have to make a full payment in advance or just paid several amount of hundred dollars for a secure deposit ?. I look forward to hearing from you soon because I will be arriving at new Zealand on Sunday morning,7th June 2009. You can just drop me the email about those kinds of information.

Yours Sincerely,

Ms.Maw
