Confirmation Letter of invitation letter by Chongqing Foreign affairs Office

Dear Ms. Nancy Croon
According to your advice for the e-mail of 18 August/2011, I contacted to the Foreign office. They said that your invitation letter attested by Notary public of Beibey district, Chongqing is enough for the use of visas of your wife, son , daughter in the Chinese Embassy of Bangladesh.
Now, my question to you, is it enough for visas ? My family members will come here for two years living with me. I would like to eagerly wait your reply very soon.

Sincerely yours
Dr. Md. Jahangir Alam , Ph.D (Japan)
