Convey news and invitations personally, if possible. Writing letters keeps contacts open, reminds officials of your interest and maintains pressure on subjects that you want to see concluded. Confine your letter to a single subject. Be concise and keep your letter to a single page, if practical. Long letters with excess wordage often are pushed aside and forgotten.
Government officials view letters with importance.
Use of your official letterhead is essential. Form letters should not be used. Make sure that you have the name of the official spelled correctly and use the proper title. If you are not sure, call his secretary or organization and verify your information. Be businesslike - brief and to the point.
