CitizenPath has created a sample cover letter to help you file Form I-751 jointly with your spouse.
This is a sample cover letter for you to use as a guide. Do not submit this letter without updating it to fit your specific situation. The example also includes references to a conditional permanent resident child. If you are not filing with a child, you can remove this reference.
The letter also lists several examples of your bona fide marriage. If these examples do not apply to you, use examples of your own. You may also add details that you believe will provide additional evidence of a valid marriage.
