Living in US on TN how to become perminte resident

I am currently on a TN visa living in the USA, my Permanent residence is still my Canada address. I am recently just became engaged. We are currently living together, what are the requirements and steps to go through to get a Permanent residence or green once we are married?

Since you are lawfully admitted to the United States in TN status, after marriage you can file for adjustment of status to a U.S. permanent resident (green card holder) through marriage to a U.S. citizen. This process is done by filing several Forms with U.S. Citizenship and Immigration Services. These include: Form I-130, Form I-485, Form I-864, among others. This process is sensitive and detail specific. It is important to complete all Forms properly and support the application with adequate evidence of the bona fides of the marriage. Failure to properly complete and include all necessary Forms and evidence will result in delays and could result in a denial.
