Will my marriage affect me in helping my mom get her papers?

No, if your mother entered the US unlawfully, she is not eligible for legalization of her status within the US regardless of whether you are married or not.

If you are a US citizen, your marital status has no bearing on your eligibility to sponsor your mother. As a US citizen, your mother is considered an immediate relative of a US citizen [you] and whether you are married or unmarried is not relevant in that consideration. But I caution that several issues are involved and must be considered when a US citizen is filing paperwork for an alien relative, including for example whether the alien is qualified to receive an immigrant visa or whether US citizen has sufficient income to show that if visa is granted, the alien will not end up on welfare. Consult with an attorney because, even if there are problems, an experienced lawyer can help you overcome issues that will otherwise make it impossible for your mother to come to the US

To sponsor one's mom, the USA citizen must be at least 21 years old. Whether the USA citizen is married or not, has no effect on the I-130 application for the mother.

More information is required, but it probably will not help her.

The short answer is probably not. There are certain factors that help in attaining citizenship, such as being married to or a child of a citizen of the United States. Having a married child in the States is not seen as as pressing of a situation as a spouse or child, unfortunately. I would recommend contacting the Michigan Non-Profit known as Justice For Our Neighbors (JFON) for free help on this issue. They serve people throughout the State of Michigan and would be able to give you all the information you need.
