Can, You did not mention who in your family. If you let me know your visa status here in USA, somebody would be able to help you out.
cheers

Some body had mentioned earlier in another thread about the following site:
www.immihelp.com
Please, go to that site. It has a lot of useful immigration related information including the sample letter you are seeking for. It is really a good site.
