We require two employer letters on a company letterhead so that we can corroborate the information provided in your CV or Resumé. Duplicate letters signed by different signatories will be treated as a single letter. Letters written on plain paper will not be accepted. If you have only worked for one company, or have worked for your company for at least five years, then a single letter will be accepted. The minimum information we need is: The date that you started working for the company, your job description, the date you left the company (or confirmation that you are still employed if you are still working for the company).  Testimonials, Relieving Letters, Offers of Employment and Reference Letters are also acceptable. Employer letters are not forwarded to the authorities, but they are referred to in your Certificate).
