Start with an introduction that clearly states your purpose and why you're writing the letter. In the middle section, provide a detailed explanation of your request or concern. Use supporting evidence to make your case as strong as possible. Finally, end your letter with a polite but firm request for action.
Mail your forms to the address listed on that form's webpage. You may send your forms through USPS, FedEx, DHL, or UPS. We encourage you to save a copy of your payment, along with any tracking number provided by the courier, for your records and so you can verify the status of its delivery.

Your letter should be addressed to the USCIS office that is responsible for your case. You can find the address on the USCIS website or by contacting the USCIS national customer service center. You should also include a clear and professional salutation, such as “Dear USCIS Officer” or “To Whom It May Concern.”

Generally, I don't want people corresponding with USCIS, unless they've been asked to do so. It's generally not a good idea to just out of the blue, write USCIS a letter. So our advice generally is to not send USCIS a letter.
