Yes they retain citizenship.
No. In the US adults regardless of their citizen status cannot be adopted. A legal immigrant can be sponsored by a US citizen for permanent residency and citizenship.
No, marrying a U.S. citizen does not automatically grant an immigrant permanent resident or citizenship status. http://www.uscis.gov
yes. it can, but not always is.
Yes, an American citizen may sponsor a same-sex Mexican spouse for a visa, permanent residency and, ultimately, citizenship.
No, she is not. She will be allowed to remain in the US with her spouse and children, but she will have to apply for citizenship separate from her marriage. The US citizen REMAINS a US citizen. The immigrant remains an immigrant and must follow the legal path to resident immigrant status, and from there to citizenship. Marriage is not a free pass to residency or citizenship.
Even American citizens who have never been convicted of anything cannot give citizenship to an immigrant. There are only four ways to become an American citizen: # Be born in the United States, # Be born anywhere but have parents who are citizens, # Complete the legal process for becoming a citizen, including meeting residency requirements, taking the test and reciting the oath, # Be made a citizen by special Act of Congress.
There are not grounds for filing a civil suit in such a situation. In addition, a foreign national whether illegal or not does become a citizen by marrying an American citizen, nor are they guaranteed permanent resident status.

Yes, an American citizen doesnt lose that citizenship when another citizenship is gained.
I believe that you're guaranteed a citizenship when you marry a citizen, but being an illegal complicates the matter.

First, there's no such thing as an illegal citizen. Second, there's no such thing as an alternative lifestyle. But if you are asking if a marriage between a gay person and an illegal immigrant of the opposite sex would be valid if it is not consummated, that depends upon the laws of the state where the marriage took place. If the marriage was made with the intent for the illegal alien to gain citizenship or permanent resident status, that won't happen. Marrying a U.S. citizen DOES NOT automatically confer citizenship or permanent resident status.
