To add: it would be kind of laughable for permanent residents to be able to go to army and die for the USA but not be able to own a gun in their house just like other citizens.

If it is legal at this moment in your state then you're allowed to get married: not that it matters from immigration perspective.
Abortion is legal in all states: there is nothing controversial about that law. Gun ownership is the same.

Shani682, I am sorry, but I doubt you know what you're talking about. You can get divorced and still file to remove conditions. So yes even if your marriage is not good in 2 years or 3 months, it doesn't matter, as long as you prove you entered it in good faith. It is when they suspect that you're lying that you're filing together when you're not or that you entered the marriage solely to receive immigration benefits, that's when the trouble begins.
And, no, you do not just get deported: there is a process and in fact it is not even up to USCIS, but immigration judge.
