That law has NEVER changed. Not having to leave the country applies ONLY to those who although currently "illegal", entered the US LEGALLY. If a person entered the US ILLEGALLY, the ONLY way to become legal through marriage to a US citizen is to return to the original country and apply for, and get, a waiver. It is IMPOSSIBLE to get this type of waiver in the US for those with illegal entry.
Follow the same procedure as if the person were a citizen rather than an illegal immigrant. File the dissolution of marriage petition in the proper court in the state where the person wishing the divorce resides.
They can certainly get married. There is normally no requirement to prove citizenship to obtain a marriage license. It does not mean they won't get deported or that they automatically get citizenship.
No, but the person you marry can sponsor your citizenship making it easier. It takes about a year, because the us citizen will be investigated and both people have to prove that it is a real marriage and not a ploy just to get citizenship.
It is illegal to give a fake marriage certificate. Married or single this person should have no problem getting a job at polytechnic at Zamboanga as librarian.
