An alien with no greencard or "papers" could get deported any time. Getting married or getting a divorce are things which, in and of themselves, have no baring on the aliens Immigration status.
If the spouse had filed a petition on the alien's behalf, the petition would no longer be valid. An immature or vindictive ex-spouse could try to make immigration trouble for the alien, but it's unlikely that they would be able to actually get the person deported.
Ask a lawyer....
Yes.
no, you must file for divorce to be legally divorsed
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.
If the divorce was lawfully conducted according to Mexican law, and a legal decree to that effect was issued then it is legal in the US.
Illegal alien stands for illegal imagrant!
No. The process is the same as it would be if the spouse were a U.S. citizen.
I believe the spousal support decision by the court in the divorce decree would take precedence here .
I do not think there is an illegal alien, but there is such thing as alien
'Illegal alien citizen' is an oxymoron.
An alien is not illegal as long as she/he has documentation of status. An alien who is documented to be a permanent resident is not illegal. If the alien does not have and never has had documentation of an immigration status, then that person is an illegal alien.
Yes it would be the same as divorcing someone who abandoned you and you did not know their whereabouts.
