I don't want my personal politics to have a negative effect on my response so I will be as clear and concise as possible.

Based on what you provided thus far I would get a lawyer and make sure that marriage will ensure she will not get deported. There is no use getting married only to watch her be deported because of some new regulation.

Now, I may not agree with how the laws are upheld, but I understand why people want them and agree with them to an extent.
