How do you write a visa extension letter?

Using the letter format on the link below, use the reference line for your visa number. In the first paragraph state why you are writing. In the second paragraph, state the facts pertinent to the extension that you are requesting. The third paragraph should state your deadline dates and information for them to contact you if they require further information from you. Be sure to list anything that you are attaching to the letter at the end of the letter (enclosures). Keep the letter as simple as one, two, three; base your reasons on facts, not emotions. Don't forget to sign the letter.
